Schematron

<sch:rule context="tei:constraintSpec[ @mode = ('add','replace') or not( @mode ) ]">
<sch:assert test="@scheme">The @scheme attribute of <constraintSpec> is required when the @mode is <sch:value-of select="if (@mode) then concat('"',@mode,'"') else 'not specified'"/>.</sch:assert>
</sch:rule>
提案する値は以下の通り:
schematron
(ISO スキマトロン)
解説

constraintSpecでのSchematron 1.xの利用は、このガイドラインでは推奨せず最近のTEIスタイルシートでもサポートしない。 それ故、schematronの値はISO SchematronがconstraintSpecで用いられることを示すのに使う。

解説

A child constraint is required when the mode attribute has the value replace or add (or is not specified, as add is the default). No child elements are permitted when the mode attribute has the value delete. At least one child element is required when the mode attribute has the value change.
例

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:rule context="tei:addSpan">
   <sch:assert test="@spanTo">The spanTo= attribute of <sch:name/> is required.</sch:assert>
  </sch:rule>
 </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:rule context="tei:figure">
   <sch:report test="not( tei:figDesc | tei:head )">You should
       provide information in a figure from which
       we can construct an alt attribute in HTML</sch:report>
  </sch:rule>
 </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="author_ne_title"
 scheme="SPITBOL">
 <constraint>
   (output = leq(title,author) "title and author cannot be the same")
 </constraint>
</constraintSpec>
