Hi,
I want to embed a Schematron validation (which allows Xpath) in XSD.
Example below is to validate "subjectLevel" element. First subjectLevel"
element should have the value "Yes" and "subjectLevel" element other than
the first position should have value "No". I tried using "xs:annotation" to
embed Schmatron rules in XSD but while validating the xml against that XSD,
I am not getting Schematron validation error.
Please let me know if there is any other approach of doing this kind of
Schematron validation inside XSD.
