Calabash: requires Saxon SA for XSD validation

  Hi,

  Is there any reason Calabash does require Saxon SA for validation
with XSD?  I guess this is because the PSVI and its integration with
XSLT SA and XQuery SA.  But because the PSVI annotations are optional
on the result of p:validate-with-xml-schema, couldn't we fallback to
Xerces in case Saxon SA is not detected, instead of failing?

  Regards,
