Thank you, Martin and Achim. Raising an error (in the next release) will
help.
For what it's worth, I did see, in the documentation, the advice that "This
is done by using -config=uri-or-path as first element on the command line",
but I misunderstood it. I was confused, when I first began using Morgana,
by how Morgana expects options to follow the name of the file being
processed, e.g., the correct *Morgana.sh **filename.xpl*
*-xslt-connector=Saxon10
*rather than the incorrect *Morgana.sh -xslt-connector=Saxon10 filename.xpl*.
I had initially expected the latter because so many other applications and
commands put command-line options (with leading "-" characters) before the
target of the operation. Having learned that Morgana wants the filename
before the options, when I read the instruction to put the *-config* option
first, I misunderstood it as "the first option, but all options still
follow the filename". Allowing options to appear in any order would be
helpful, but I understand that parsing command-line options can be a time
sink, and that the effort that would require might better be applied to
functionality and features.
In any case, changing the order enabled Morgana to find the SchXSLT XSLT
stylesheets, although only to yield a null pointer exception:
djb@koala-4 adj % zsh
/opt/morgana/MorganaXProc-IIIse-0.9.4.2-beta/Morgana.sh
-config=/opt/morgana/MorganaXProc-IIIse-0.9.4.2-beta/config.xml adj.xpl
-xslt-connector=Saxon10 -xquery-connector=Saxon10

It does this both with the real Schematron and with a minimal test
Schematron file (that is, one that never matches anything in the document),
so I don't think the Schematron file is the source of the problem. I'm not
sure where to look next. The beginning of the XProc is:
<!-- ================================================================ -->
<!-- Set up primary ports -->
<!-- -->
<!-- Source is empty because it is read with XQuery set -->
<!-- ================================================================ -->
<p:input port="source" sequence="true">
<p:empty/>
</p:input>
<p:output port="result" sequence="true"/>
<!-- ================================================================ -->
<!-- Read, filter, and wrap adjectives -->
<!-- ================================================================ -->
<p:identity message="Selecting adjectives from dictionary"/>
<p:xquery>
<p:with-input port="query">
<p:inline content-type="application/xml">
<words>{{doc("../../dictionary.xml")/words/item[type/@partOfSpeech
eq "A"]}}</words>
</p:inline>
</p:with-input>
</p:xquery>
<!-- ================================================================ -->
<!-- Verify that all paradigms in dictionary are in paradigms file -->
<!-- ================================================================ -->
<p:identity message="Verifying that all paradigms in dictionary are in
paradigms file"/>
<p:validate-with-schematron>
<p:with-input port="schema" href="adj-paradigms-in-dictionary.sch"/>
</p:validate-with-schematron>
The files all exist in the designated locations (the Schematron file is in
the same directory as the XProc). If I remove the Schematron validation
step and move to the next one, which applies an XSLT transformation, it
works correctly, which confirms that the input is being read correctly.
If it looks as if I'm missing something (else) that should be obvious, I
would be grateful for a nudge.
Best,
David
