This constraint uses Schematron to enforce the presence of the spanTo attribute (which comes from an attribute class) on the addSpan element:

<constraintSpec ident="demo-c1"
 scheme="schematron">
 <desc>Enforce the presence of the <att>spanTo</att> attribute</desc>
 <constraint>
  <sch:assert test="@spanTo">The spanTo= attribute of <sch:name/>
     is required.</sch:assert>
 </constraint>
</constraintSpec>
例
<constraintSpec ident="demo-c2"
 scheme="schematron">
 <desc>Implement an accessibility rule which says that pictures should
   have textual explanations</desc>
 <constraint>
  <sch:report test="not(tei:figDesc or tei:head)"> You should
     provide information in a figure from which
     we can construct an alt attribute in HTML </sch:report>
 </constraint>
</constraintSpec>
例

This constraint uses SPITBOL (a language which is not expressed in XML) to check whether the title and author are identical:

<constraintSpec ident="local"
 scheme="SPITBOL">
 <constraint>
   (output = leq(title,author) "title and author cannot be the same")
 </constraint>
</constraintSpec>
