[PATCH v2] msxml3: use XSD regex quantifier format S{0, m} instead of S{, m}

[Damjan Jovanovic]

S{,m} is invalid in libxml2 2.9.11 and later, and was never valid
in the XSD specification or any XML implementation tested. We
should only use S{0,m} for our internal XSD schema used in XDR validation.

Try 2 adds a test.
