xs:sequence Xerces does not select correct sequence during validation
Summary: xs:sequence Xerces does not select correct sequence
during validation
Product: Xerces2-J
Version: 2.5.0
Platform: PC
OS/Version: Windows NT/2K
Status: NEW
Severity: Critical
Priority: Other
Component: SAX
AssignedTo: xerces-j-dev@xml.apache.org
ReportedBy: xerces@postbox.to
The following schema and instance document are valid according to XMLSpy 5.0 ,
however Xerces fails to validate the document correctly. The problem is with
the third element of the schema , which Xerces does not process correctly.
Xerces appears to get confused with multiple consecutive elements having the
same name but slightly different signatures. Xerces does not recognise which
xs:sequence the instance document is to validate against.
The error returned by Xerces is:
Line 16 , Column 13 : cvc-complex-type.2.4.a: Invalid content was found
starting with element 'LastName'. One of '{"":Gender}' is expected
The example schema is:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:element name="Base">
