Yes, libxml2 does support complex type derivation by extension. I am aware of one bug inside libxml2 schema processing, but that is with simple-list-type extensions, and it does not apply in your case. > Do I need to tweak my validation code ? I think so. Your instance document with your attached schema validates fine with xmllint (libxml2 validation tool): $ xmllint --noout zoo.xml --schema zoo.xsd zoo.xml validates I wrote a sample program (in C) to attempt to mimic what you have, and was able to successfully validate the instance against the schema you provided. $ ./zoo zoo.xml zoo.xsd Attempting to validate zoo.xml with zoo.xsd Document in zoo.xml is valid One thing I would suggest is NOT releasing any of the resources associated with the schema before validation (do that after, instead). > //xmlSchemaFree(schema); causes crash when we try to use validCtxt > xmlSchemaFreeParserCtxt(parserCtxt); > xmlFreeDoc(schemaDoc); > > // > http://www.xmlsoft.org/html/libxml-xmlschemas.html#xmlSchemaValidateDoc > int error = xmlSchemaValidateDoc(validCtxt.validCtxt, doc); > > if (error == 0) { > NSLog(@"document is a valid instance of %@", schemaFileName); > ret = YES; > } Also, what's the difference between passing validCtxt instead of validCtxt.validCtxt into the xmlSchemaValidateDoc() function?
