xs:long

A 64-bit two’s complement integer value between -2⁶³ and 2⁶³ - 1.

xs:NCName

NCName or “Non-colonized” name is a more restrictive type than xs:string that is used as a base for names and identifiers. It starts with a letter or underscore and can be followed by a letter, digit, ‘.’, ‘-’, or ‘_’.

NCName     ::= (Letter | '_') (NCNameChar)*
NCNameChar ::= Letter | Digit | '.' | '-' | '_' | CombiningChar | Extender

xs:positiveInteger

An integer with a minimum value of 1.

For a complete definition, refer to XML Schema Part 2: Datatypes – 3.3.25 positiveInteger .

xs:string

An XML character string where every character has a corresponding Universal Character Code point. String can be further constrained by length or to match a regular expression pattern. Most attributes in PSML have a maximum length.
