Note

When used in a specification element such as elementSpec, TEI convention requires that this be expressed as a finite clause, begining with an active verb.
Example

Example of a desc element inside a documentation element.

<dataSpec module="tei"
 ident="teidata.point">
 <desc versionDate="2010-10-17"
  xml:lang="en">defines the data type used to express a point in cartesian space.</desc>
 <content>
  <dataRef name="token"
   restriction="(-?[0-9]+(\.[0-9]+)?,-?[0-9]+(\.[0-9]+)?)"/>
 </content>
<!-- ... -->
</dataSpec>
Example

Example of a desc element in a non-documentation element.

<place xml:id="KERG2">
 <placeName>Kerguelen Islands</placeName>
<!-- ... -->
 <terrain>
  <desc>antarctic tundra</desc>
 </terrain>
<!-- ... -->
</place>
Schematron A desc with a type of deprecationInfo should only occur when its parent element is being deprecated. Furthermore, it should always occur in an element that is being deprecated when desc is a valid child of that element.

<sch:rule context="tei:desc[ @type eq 'deprecationInfo']">
<sch:assert test="../@validUntil">Information about a
deprecation should only be present in a specification element
that is being deprecated: that is, only an element that has a
@validUntil attribute should have a child <desc
type="deprecationInfo">.</sch:assert>
</sch:rule>
