Schematron: Is @documents of an abstract pattern subject to parameterrep

[David Maus <lists@dmaus.name>]

Hello all,

Schemtron 2016 added an optional @documents attribute to sch:pattern
that provides IRIs of subordinate document the rule contexts are
relative to. The @documents is also allowed on an abstract pattern as
per grammar in Annex A.

Am I right to assume that the @documents is subject to parameter
replacement when creating an instance of an abstract pattern?

I.e. does

#+BEGIN_SRC xml
  <schema xmlns="http://purl.oclc.org/dsdl/schematron"; queryBinding="xslt2">
    <pattern abstract="true" id="abstract-pattern" documents="'$filename'">
      <rule context="/">
        <assert test="true()"/>
      </rule>
    </pattern>
    <pattern is-a="abstract-pattern" id="instance">
      <param name="filename" value="foobar.xml"/>
    </pattern>
  </schema>
#+END_SRC

expands into

#+BEGIN_SRC xml
  <schema xmlns="http://purl.oclc.org/dsdl/schematron"; queryBinding="xslt2">
    <pattern abstract="true" id="abstract-pattern" documents="'$filename'">
      <rule context="/">
        <assert test="true()"/>
      </rule>
    </pattern>
    <pattern id="instance" documents="'foobar.xml'">
      <rule context="/">
        <assert test="true()"/>
      </rule>
    </pattern>
  </schema>
#+END_SRC

?
