Subject: Error processing DocBook assemblies with XProc (Calabash): "There is no Saxon extension function with the local name node-set"
Hi there,
I'm not quite sure whether this is a DocBook question or a
Calabash/XProc one, but given that there's a substantial overlap between
the developers and users of both, hopefully someone will be able to
answer it here.
I'm processing DocBook 5.1 assembly files with the DocBook namespace
stylesheets version 1.78.0. Using Saxon 8.7 and the
'assembly/assemble.xsl' stylesheet, I can turn my assemblies into
'consolidated' DocBook articles, books (or whatever).
However, when I apply the same XSLT transformation using Calabash XProc,
I get the following error:

Here's the XSLT step in question from my XProc script:
<p:xslt name="assemble-docbook">
<p:input port="stylesheet">
<p:document
href="../target/generated-resources/docbook/assembly/assemble.xsl"/>
</p:input>
<p:input port="parameters">
<p:empty/>
</p:input>
</p:xslt>
The input to this step (the 'source' port) is a DocBook assembly
document, with all the necessary 'resource' elements defined, and a
single 'structure' element which references them. The 'stylesheet' port
references the DocBook 1.78.0 assemble.xsl stylesheet.
I'm using the following Calabash version:
XML Calabash version 1.0.3 (for Saxon 9.4.x), an XProc processor.
Running on Saxon version 9.4.0.2, HE edition.
I'd appreciate any guidance on what might be going wrong.
Thanks,
Graeme
