Ok, thanks Kasimier for this good pointer to the test suite file "xstc/xstc.py".
So here are the steps (note that in xstc.py the error cases are properly
handled)

import libxml2
ctxt = libxml2.schemaNewParserCtxt("my-schema.xsd")
schema = ctxt.schemaParse()
del ctxt
validationCtxt = schema.schemaNewValidCtxt()
doc = libxml2.parseFile("test.xml")
#instance_Err = validationCtxt.schemaValidateFile(filePath, 0)
instance_Err = validationCtxt.schemaValidateDoc(doc)
del validationCtxt
del schema
doc.freeDoc()
if instance_Err != 0:
print "VALIDATION FAILED"
else:
print "VALIDATED"

I'm heading home, so just a short one: maybe the test suite
file "xstc/xstc.py" can be of some help; it uses schemaValidateDoc()
as well as schemaValidateFile() for stream-based validation.
