Are abstract patterns supported by the Schematron implementation in Arbortext? I wrote the following simple abstract pattern, and it appears not to compile when running completeness check.
<pattern abstract="true" id="conditionsValidation">
<title>Element count validation</title>
<rule context="$element[not(@conditions)]">
<report test="preceding-sibling::$element[not(@conditions)]">XisError: More than one <name/> found. Set the @condition attribute to ensure only one appears in output.</report>
</rule>
</pattern>
<pattern is-a="conditionsValidation">
<param name="element" value="leadIn"/>
</pattern>
