Usage context

Attributes

This element includes the following attributes:

@id

A fragment identifier that is unique within the document.

@mediatype

The media type (MIME) of the content within the media fragment. 

It must not include character encoding (charset) as the encoding is defined at the PSML document level.

Media types referring to binary documents are acceptable, provided that they use an encoding that is compatible with the character encoding used at the PSML document level. In general, it is best to use base64.

@type

If this fragment has a type or was created using a document-template.

Examples

Example 1: Plain text fragment

<media-fragment id="1" mediatype="text/plain">
  Here is some plain text content
</media-fragment>

Example 2: MathML fragment

Media fragments can be used to include MathML  in PSML document.

<media-fragment id="1" mediatype="application/mathml+xml">
  <mrow>
    <mfrac>
      <mrow>
        <mi>x</mi>
        <mo>+</mo>
        <msup>
          <mi>y</mi>
          <mn>2</mn>
        </msup>
      </mrow>
      <mrow>
        <mi>k</mi>
        <mo>+</mo>
        <mn>1</mn>
      </mrow>
    </mfrac>
  </mrow>
</media-fragment>

Example 3: SVG

Media fragments can also be used to include SVG  inside PSML.

<media-fragment id="1" mediatype="image/svg+xml">
  <svg xmlns="http://www.w3.org/2000/svg" version="1.1">
 
    <rect x="50" y="50" width="200" height="200" fill="lime" />
    <circle cx="125" cy="125" r="75" fill="orange" /> 
    <line x1="50"
          y1="50"
          x2="200"
          y2="200"
          stroke="blue"
          stroke-width="4"/>
