DTDs and Attribute Expansion

Hi,

I'm playing around with DTDs and attribute expansion (or, rather, suppression thereof). In Morgana, this will suppress expansion.

<p:declare-step xmlns:p="http://www.w3.org/ns/xproc"
                xmlns:xs="http://www.w3.org/2001/XMLSchema"
                xmlns:mox="http://www.xml-project.com/morganaxproc"
                version="3.0">

  <p:output port="result" serialization="map{'indent': true()}"/>

  <p:load href="inputs/04-boxed-text-jats.xml">
    <p:with-option name="parameters" select="map{
      xs:QName('mox:expand-default-attributes'): false()
    }"/>
  </p:load>

  <p:identity/>

</p:declare-step>

1. This only works on p:load. As far as I see, even if Achim wanted to implement the same mechanism on p:input, that wouldn't work there as p:input won't take parameters.

2. Is there a simimlar mechanism for calabash? I couldn't find anything in the documentation.

Best,
Denis
