<content>

<content> (content model) contains a declaration of the intended content model for the element (or other construct) being specified. [23.5 Element Specifications]
Module tagdocs — Documentation Elements
Attributes
autoPrefix⚓︎ controls whether or not pattern names generated in the corresponding RELAX NG schema source are automatically prefixed to avoid potential nameclashes.
Status Optional
Datatype teidata.truthValue
Legal values are:
true
Each name referenced in e.g. an <rng:ref> element within a content model is automatically prefixed by the value of the prefix attribute on the current schemaSpec [Default]
false
No prefixes are added: any prefix required by the value of the prefix attribute on the current schemaSpec must therefore be supplied explicitly, as appropriate.
Contained by
tagdocs: dataSpec elementSpec macroSpec moduleRef
May contain ANY
Note

It is required that the content element has only one child element. If several RELAX NG elements are desired, they must be wrapped in a <rng:div>.
Example

This sample content element indicates that the element being specified has no content:

<content>
 <empty/>
</content>
Example

This content element defines a content model, expressed directly in the TEI ODD language, that allows either a sequence of paragraphs or a series of msItem elements optionally preceded by a summary:

<content>
 <alternate>
  <classRef key="model.pLike"
   maxOccurs="unbounded"/>
  <sequence>
   <elementRef key="summary" minOccurs="0"
    maxOccurs="1"/>
   <elementRef key="msItem"
    maxOccurs="unbounded"/>
  </sequence>
 </alternate>
</content>
Example

This sample content element defines a content model, expressed in the RELAX NG schema language, that allows either a sequence of paragraphs or a series of msItem elements optionally preceded by a summary:

<content>
 <rng:choice>
  <rng:oneOrMore>
   <rng:ref name="model.pLike"/>
  </rng:oneOrMore>
  <rng:group>
   <rng:optional>
    <rng:ref name="summary"/>
   </rng:optional>
