Boris Kolpackov commented on XERCESC-1281: ------------------------------------------ Any plans to fix this for 3.0.0? > Validation by restriction doesn't take into account substitution groups > ----------------------------------------------------------------------- > > Key: XERCESC-1281 > URL: http://issues.apache.org/jira/browse/XERCESC-1281 > Project: Xerces-C++ > Type: Bug > Components: Validating Parser (Schema) (Xerces 1.5 or up only) > Versions: 2.5.0 > Environment: Windows XP, Visual C++ 6.0 > Reporter: Alberto Massari > Attachments: rT.xml, restrictionTest.xsd > > Running SaxCount -n -f -s rT.xml shows the following errors: > Error at file c:\testcase\schema-restriction/restrictionTest.xsd, line 42, > char 30 > Message: Recurse: There is not a complete functional mapping between the > particles > Error at file c:\testcase\schema-restriction/restrictionTest.xsd, line 63, > char 30 > Message: Forbidden restriction of 'choice': All,Seq,Leaf > The first error is caused by a restriction of A1_Type, replacing a sequence > of O1 with a sequence of O2, O2 being in the substitution group of O1. > The second error is caused by a restriction of B1_Type, replacing a sequence > of O1 with a sequence of a choice of O2.
