++4.9.3+
++======
++
++* 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.

+ 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.
++The module constant ``lxml.isoschematron.schematron_schema_valid_supported`` can be used
++since lxml 4.9.2-8 to detect whether schema file validation is available.
