Schematron

<constraintSpec xmlns:sch="http://purl.oclc.org/dsdl/schematron" scheme="schematron" ident="one-constraintDecl-per-scheme" xml:lang="en">
    
    <constraint>
      <sch:rule context="/*[ count( //tei:constraintDecl ) gt 1 ]">
        <sch:let name="schemes" value="//tei:constraintDecl[ not(ancestor::*[local-name(.) eq 'egXML'] ) ]/@scheme"/>
        <sch:let name="disctinct_schemes" value="distinct-values( $schemes )"/>
        <sch:assert test="count( $schemes ) eq count( $disctinct_schemes )">
          Each &lt;constraintDecl&gt; element should have a @scheme attribute that is distinct from that of all the other &lt;constraintDecl&gt;s.
        </sch:assert>
      </sch:rule>
    </constraint>
  </constraintSpec>
