xsd:redefine recently broken
----------------------------
Key: XERCESC-1544
URL: http://issues.apache.org/jira/browse/XERCESC-1544
Project: Xerces-C++
Type: Bug
Components: Validating Parser (Schema) (Xerces 1.5 or up only)
Versions: 2.7.0
Environment: MacOS X, g++ build
Reporter: Jerry Carter
The W3C schema for VoiceXML is quite complex and makes a good test of Xerces.
Previous versions worked well, but 2.7.0 has some problems. In addition the
regexp issues (bug 1512), xsd:redefine is also broken. This has worked in
previous versions (up through 2.6.0, I believe).
The main VXML schema <http://www.w3.org/TR/voicexml21/vxml.xsd> eventually
includes <http://www.w3.org/TR/voicexml21/vxml-synthesis-extension.xsd>.
There, on line 28 is the problem statement:
<xsd:redefine schemaLocation="vxml-synthesis-restriction.xsd">
This generates two classes of error messages.
1: Message: Could not find a declaration in the schema to be redefined
corresponding to '...'
2: Message: Global complexType:'...' declared more than once or also declared
as simpleType
