<sch:pattern id="declarable" abstract="true">

<!-- parameter 'tde' is for "this declarable element (type)" -->
<sch:rule context="$tde[ ancestor::tei:teiHeader and following-sibling::$tde and not( preceding-sibling::$tde ) ]">
 <sch:report test="../child::$tde[ not( @xml:id ) ]"> When there is more than one <sch:name/>, each must have an @xml:id

Note

The rules governing the association of declarable elements with individual parts of a TEI text are fully defined in chapter 16.3 Associating Contextual Information with a Text. Only one element of a particular type may have a default attribute with a value of true.
