<tagsDecl>

<tagsDecl> (tagging declaration) provides detailed information about the tagging applied to a document. [2.3.4 The Tagging Declaration 2.3 The Encoding Description]
Module header — The TEI Header
Attributes
partial⚓︎ indicates whether the element types listed exhaustively include all those found within text, or represent only a subset.
Status Recommended
Datatype teidata.truthValue
Note

TEI recommended practice is to specify this attribute. When the tagUsage elements inside tagsDecl are used to list each of the element types in the associated text, the value should be given as false. When the tagUsage elements inside tagsDecl are used to provide usage information or default renditions for only a subset of the elements types within the associated text, the value should be true.

Example
<tagsDecl partial="true">
 <rendition xml:id="rend-it" scheme="css"
  selector="emph, hi, name, title">font-style: italic;</rendition>
 <namespace name="http://www.tei-c.org/ns/1.0">
  <tagUsage gi="hi" occurs="467"/>
  <tagUsage gi="title" occurs="45"/>
 </namespace>
 <namespace name="http://docbook.org/ns/docbook">
  <tagUsage gi="para" occurs="10"/>
 </namespace>
</tagsDecl>

If the partial attribute were not specified here, the implication would be that the document in question contains only hi, title, and <para> elements.
