I ran it successfully on Windows with BaseX 8.6.5 and schematron-basex 1.2, both when I used proper file: URIs and Windows file system paths with backslashes.

I used both the version of /docbook-mods.sch.xml that you sent me and a version with expanded entities (using xmllint --noent --dropdtd first).

When I gave it too little stack size (-Xss108k) on startup, I could only provoke a "Stack Overflow: Try tail recursion?" BaseX error, not the "Too many nested template calls" Saxon error that you reported. Calling Saxon directly for applying iso_dsdl_include.xsl on the schema was also successful if heap and stack sizes were large enough.

What happens when you apply your Saxon EE standalone, transforming the schema with iso_dsdl_include.xsl?

Which version of Saxon 9 EE are you using?

Is saxon9he.jar or another Saxon version on the classpath as per

?
The Schematron schema says queryBinding="xslt2" and this requires an
XSLT 2 processor.
