PageSeeder datatypes

PageSeeder datatypes extend primitive types and are constrained by a pattern or by enumerated values. For readability, the following conventions are used.

Character definitions used in this article
Letters	[A-Za-z]	ASCII letter in upper case and lower case
Digits	[0-9]	ASCII digits 0 to 9
Underscore	_	Underscore ASCII character U+005F
Hyphen	-	Hyphen-minus ASCII character U+002D
Dot	.	Full stop or baseline dot character U+002E

Boolean

An xs:boolean value can only be one of the canonical boolean values of true or false.

PageSeeder does not extends the XML Schema xs:boolean datatype to support literal values 1 or 0.

<xs:simpleType name="boolean">
  <xs:restriction base="xs:boolean">
    <xs:pattern value="true|false"/>
  </xs:restriction>
</xs:simpleType>

Document ID

The document ID is an xs:string that only contains letters, digits, underscores or hyphens and must not exceed 100 characters.

<xs:simpleType  name="document-id">
  <xs:restriction base="xs:string">
    <xs:pattern value="[a-zA-Z0-9_\-]+"/>
  </xs:restriction>
</xs:simpleType>

Document level

The document level is one of three values metadata, portable or processed.

Only portable documents can be uploaded to PageSeeder; but PageSeeder can generate documents in metadata or processed level.

<xs:simpleType>
  <xs:restriction base="xs:string">
    <xs:enumeration value="metadata"/>
    <xs:enumeration value="portable"/>
    <xs:enumeration value="processed"/>
  </xs:restriction>
</xs:simpleType>

Document title

Also known as URI title, the title of a document title is an xs:string which must not exceed 250 characters.

<xs:simpleType>
  <xs:restriction base="xs:string">
    <xs:maxLength value="250"/>
  </xs:restriction>
</xs:simpleType>

Document type

The document type is an xs:string that only contains letters, digits or underscores and must not exceed 50 characters.

<xs:simpleType name="document-type">
  <xs:restriction base="xs:string">
    <xs:pattern value="[a-zA-Z0-9_]+"/>
  </xs:restriction>
</xs:simpleType>

Fragment ID

The fragment ID is an xs:string that only contains letters, digits, underscores, equals, commas, ampersands, hyphens or dots and must not exceed 250 characters.

<xs:simpleType name="fragment-id">
  <xs:restriction base="xs:string">
    <xs:pattern value="[a-zA-Z0-9_=,&amp;\-\.]+"/>
  </xs:restriction>
</xs:simpleType>

Fragment type

The fragment type is an xs:string that only contains letters, digits, underscores, hyphens or dots.

<xs:simpleType name="fragment-type">
  <xs:restriction base="xs:string">
    <xs:pattern value="[a-zA-Z0-9_\-\.]+"/>
  </xs:restriction>
</xs:simpleType

Heading level

The heading level is an xs:integer value between 1 and 6.

<xs:simpleType>
  <xs:restriction base="xs:integer">
    <xs:pattern value="[1-6]"/>
  </xs:restriction>
</xs:simpleType>

Horizontal alignment

An enumerated value used for attributes to determine the horizontal alignment of the text content.

It must be one of the following values: left, center, right, justify. Usually the value left is the default.

More formally, this type is defined as:

<xs:simpleType>
  <xs:restriction base="xs:string">
    <xs:enumeration value="left" />
    <xs:enumeration value="center" />
    <xs:enumeration value="right" />
    <xs:enumeration value="justify" />
  </xs:restriction>
</xs:simpleType>

Indent

The indent level is an xs:integer value between 1 and 6.

<xs:simpleType>
  <xs:restriction base="xs:integer">
    <xs:pattern value="[1-6]"/>
  </xs:restriction>
</xs:simpleType>

Label

The @label datatype extends xs:string but can only contain the following characters [a-zA-Z0-9_-].

There is no limit on the length of a label – it is recommended that the name of a label does not exceed 245 characters.

<xs:simpleType name="label">
  <xs:restriction base="xs:string">
    <xs:pattern value="[a-zA-Z0-9_\-]+"/>
  </xs:restriction>
</xs:simpleType>

Label list

An unordered comma-separated list of label names.

Empty and duplicate label names are ignored, so the note,important,important, is semantically equivalent to important,note.

<xs:simpleType name="label-list">
  <xs:restriction base="xs:string">
    <xs:pattern value="[a-zA-Z0-9_\-,]*"/>
  </xs:restriction>
</xs:simpleType>

List type (ordered)

The list type determines what prefix is displayed before each item. The list type is used for predetermined prefixes. It's possible to use custom schemes using the @role attribute.

Prefixes for each list type
Type	Prefixes
`arabic`	1 2 3 4 5 ...
`upperalpha`	A. B. C. D. E. ...
`loweralpha`	a. b. c. d. e. ...
`upperroman`	I II III IV V ...
`lowerroman`	i ii iii iv iv ...

<xs:simpleType>
  <xs:restriction base="xs:string">
    <xs:enumeration value="arabic"/>
    <xs:enumeration value="upperalpha"/>
    <xs:enumeration value="loweralpha"/>
    <xs:enumeration value="upperroman"/>
    <xs:enumeration value="lowerroman"/>
  </xs:restriction>
</xs:simpleType>

List type (unordered)

The list type determines the bullet style of each list item. This list type is used as a fallback. It’s possible and often preferable to define the bullet style externally (for example in CSS, or Word template properties when PSML is converted to HTML or DOCX).

<xs:simpleType>
  <xs:restriction base="xs:string">
    <xs:enumeration value="none"/>
    <xs:enumeration value="disc"/>
    <xs:enumeration value="circle"/>
    <xs:enumeration value="square"/>
  </xs:restriction>
</xs:simpleType>

Length

The length is the width or height of an object in pixels or percent, or more formally:

[0-9\.]+(px|%)?

Length (fixed)

The fixed length of an object is numeric value that corresponds to the length in pixels.

Port number

The port number of a URI.

<xs:simpleType>
  <xs:restriction base="xs:positiveInteger">
    <maxInclusive value="65535"/>
  </xs:restriction>
</xs:simpleType>

Property count

The property count defines the maximum number of values that the property can have.

<xs:simpleType>
  <xs:restriction base="xs:string">
    <xs:pattern value="[0-9n]+"/>
  </xs:restriction>
</xs:simpleType>

Publication ID

The publication ID is an xs:string that only contains letters, digits, underscores or hyphens and must not exceed 250 characters.

<xs:simpleType name="publication-id">
  <xs:restriction base="xs:string">
    <xs:pattern value="[a-zA-Z0-9_\-]+"/>
  </xs:restriction>
</xs:simpleType>

Publication type

The publication type is an xs:string that only contains letters, digits or underscores and must not exceed 50 characters.

<xs:simpleType name="publication-type">
  <xs:restriction base="xs:string">
    <xs:pattern value="[a-zA-Z0-9_]+"/>
  </xs:restriction>
</xs:simpleType>

Role

The role of an object is an xs:string that only contains letters, digits, underscores and hyphens.

<xs:simpleType name="role">
  <xs:restriction base="xs:string">
    <xs:pattern value="[a-zA-Z0-9_\-]+"/>
  </xs:restriction>
</xs:simpleType>

Section ID

The section ID is an xs:string that only contains letters, digits, underscores, hyphens or dots.

<xs:simpleType name="section-id">
  <xs:restriction base="xs:string">
    <xs:pattern value="[a-zA-Z0-9_\-\.]+"/>
  </xs:restriction>
</xs:simpleType>

Table part

The part of the table the row or column belongs to.

Meaning of table part on <row> or <col>
Value	Row	Column
`body`	implied default value and provided for completeness (it needn't be used)
`header`	Is part of the table header (e.g. inside `<thead>` in HTML)	Cells in the column are considered to be header cells. (e.g. `<th>` in HTML)
`footer`	Is part of the table footer (e.g. inside `<tfoot>` in HTML)	Cells in the column are considered to be footer cells. This is used for columns to right-hand side of a table that might represent aggregate values of the cells to their left (e.g. Total column)

<xs:simpleType>
  <xs:restriction base="xs:string">
    <xs:enumeration value="body" />
    <xs:enumeration value="header" />
    <xs:enumeration value="footer" />
  </xs:restriction>
</xs:simpleType>

URL type

The url type is an xs:string that only contains letters, digits or underscores and must not exceed 50 characters.

<xs:simpleType name="document-type">
  <xs:restriction base="xs:string">
    <xs:pattern value="[a-zA-Z0-9_]+"/>
  </xs:restriction>
</xs:simpleType>

Vertical alignment

An enumerated value used for attributes to determine the vertical alignment of the text content. It must be one of the following values: top, middle, bottom, baseline. Usually the value baseline is the default.

More formally, this type is defined as:

<xs:simpleType>
  <xs:restriction base="xs:string">
    <xs:enumeration value="top" />
    <xs:enumeration value="middle" />
    <xs:enumeration value="bottom" />
    <xs:enumeration value="baseline" />
  </xs:restriction>
</xs:simpleType>

Xref config

The configuration name for an xref of a certain kind, see xref-config.xml.

<xs:simpleType name="xref-config">
  <xs:restriction base="xs:string">
    <xs:pattern value="[a-zA-Z0-9\-_]+"/>
  </xs:restriction>
</xs:simpleType>

Xref display

An xs:string value determines the display of a cross-reference.

When PageSeeder resolves a cross-reference, the textual content of an inline xref is affected. This is the reason why the textual content of an xref is considered informational.

`Value`	`Effect`
`document`	The URI title of the target document: `[document title]`
`document+manual`	The URI title of the target document, followed by some manual text: `[document title]: [manual title]`
`document+fragment`	The URI title of the target document, followed by the fragment ID: `[document title]: [target fragment ID]`
`manual`	Only the manual text: `[manual title]`
`template`	The manual title (`@title` on the xref) can contain any combination of text and the following tokens which are replaced dynamically: `{document}`: display title of the target document. `{filename}`: filename of the target document. `{docid}`: docid of the target document. `{fragment}`: target fragment ID. `{prefix}`: the `@prefix` of the first heading or para in the target fragment (`<xref>` only). `{parentnumber}`: the number of the parent heading or para for the target fragment (`<xref>` only). `{heading}`: the text of the first heading or property (before `<para>`) in the target fragment (`<xref>` only). The property can not have type `markdown` or have multiple values. The `{prefix}`, `{parentnumber}` and `{heading}` can be used with each other but are not to be used in the same title with other tokens or in `<blockxref>`. They are also not to be used in xrefs that are part of headings, as they are not resolved by the table of contents.

The display attribute only affects the forward direction, reverse cross-references must use a fixed reverse title.

<xs:simpleType>
  <xs:restriction base="xs:string">
    <xs:enumeration value="document" />
    <xs:enumeration value="document+manual" />
    <xs:enumeration value="document+fragment" />
    <xs:enumeration value="manual" /> 
    <xs:enumeration value="template" />
  </xs:restriction>
</xs:simpleType>

Xref level

The level of an xref indicates how the heading levels in the target document are affected.

<xs:simpleType>
  <xs:restriction base="xs:integer">
    <xs:pattern value="[1-5]"/>
  </xs:restriction>
</xs:simpleType>

Xref type

The type of cross-reference in the forward direction.

Type	Effect
`none`	Defines a reference between the source and the target content much like a regular link.
`alternate`	An alternate representations of the current document
`math`	An in-line transclude link to a file or `<media-fragment>` with mediatype of `application/mathml+xml` or `text/asciimath`. Used for equations. Only allowed on `<xref>`.
`embed`	Indicates that the target content is intended to be embedded in place of the link during publishing or some post-processing. Only allowed on `<blockxref>`.
`transclude`	Indicates that the target content is to be included in place of the link whenever the document is viewed. Only allowed on `<blockxref>`.

See article on transclusion for a discussion on the differences between embedded links and transclusions.
The model for <xref> is the following:

<xs:simpleType>
  <xs:restriction base="xs:string">
    <xs:enumeration value="none"/>
    <xs:enumeration value="alternate"/>
    <xs:enumeration value="math"/>
  </xs:restriction>
</xs:simpleType>

The model for <blockxref> is the following:

<xs:simpleType>
  <xs:restriction base="xs:string">
    <xs:enumeration value="none"/>
    <xs:enumeration value="alternate"/> 
    <xs:enumeration value="embed"/>
    <xs:enumeration value="transclude"/>
  </xs:restriction>
</xs:simpleType>
