Subject: [PATCH] Skip test_isoschematron.test_schematron_invalid_schema_empty
without the RNG file

Subject: [PATCH] Make the validation of ISO-Schematron files optional in lxml,
depending on the availability of the RNG validation file. Some lxml
distributions discard the validation schema file due to licensing issues.

==============
+4.9.2+
+======
+
+* LP#2024343: The validation of the schema file itself is now optional in the
+ ISO-Schematron implementation. This was done because some lxml distributions
+ discard the RNG validation schema file due to licensing issues. The validation
+ can now always be disabled with ``Schematron(..., validate_schema=False)``.
+ It is enabled by default if available and disabled otherwise. The module
+ constant ``lxml.isoschematron.schematron_schema_valid_supported`` can be used
+ to detect whether schema file validation is available.

@@ -615,6 +615,15 @@ The usage of validation phases is a unique feature of ISO-Schematron and can be
a very powerful tool e.g. for establishing validation stages or to provide
different validators for different "validation audiences".
+Note: Some lxml distributions exclude the validation schema file due to licensing issues.
+Since lxml 4.9.2-8, the validation of the user provided schema can be disabled with
+``Schematron(..., validate_schema=False)``.
+It is enabled by default if available and disabled otherwise. Previous versions of
+lxml always had it enabled and failed at import time if the file was not available.
+Thus, some distributions chose to remove the entire ISO-Schematron support.
