Using SaxonC 11.4 (using HE) under Windows using Windows like file paths with a backslash works fine for me e.g. the code below using Schxslt 1.9.4 and some Schematron schema and some sample XML gives me an SVRL report output.

With SaxonC 11.99 (also using HE) under Windows it seems all those paths don't work, I don't get any error output from my attempts to check for exception_occurred but the first attempt to compile_stylesheet doesn't seem to have returned anything as the line trying to use compiled_schema = compiled_schxslt.apply_templates_returning_string(source_file = sample_schematron) gives an error AttributeError: 'NoneType' object has no attribute 'apply_templates_returning_string.

Interestingly enough if I change all my file paths to use a forwards slash in the paths as the separator (e.g.

schxslt_dir = r'C:/Users/marti/OneDrive/Documents/schematron/schxslt-1.9.4/2.0'
schxslt_xslt = r'pipeline-for-svrl.xsl'

sample_xml = r'C:/Users/marti/OneDrive/Documents/schematron/streaming/examples/BookPrice/books.xml'
sample_schematron = r'C:/Users/marti/OneDrive/Documents/schematron/streaming/examples/BookPrice/price.sch'

) the code runs fine with SaxonC 11.99.

Is that a known and intended change or limitation for SaxonC 12 (11.99) under Windows that file paths need to use a forwards slash / as the separator?
