William Eliot Kimber commented on XERCESJ-1670:
-----------------------------------------------
This bug is hit by anybody trying to constrain the DITA 1.3 XSDs to modify
attribute groups as the 1.3 XSDs currently do not have named types for
attributes with enumerated lists (we did in 1.2 but due to an oversight those
got left out of the 1.3 XSDs, which were initially generated from
newly-constructed RNGs that did not have patterns corresponding to the groups
in the 1.2 XSDs).
The DITA Open Toolkit and many other DITA processors use Xerces for parsing so
this could be a blocker for many DITA users who use the DITA XSDs and need to
redeclare attribute value enumerations, which is a pretty common customization.
> Cannot properly redefine attribute group which is not directly in the
> redefined schema

> Key: XERCESJ-1670
> URL: https://issues.apache.org/jira/browse/XERCESJ-1670
> Project: Xerces2-J
> Issue Type: Bug
> Components: XML Schema 1.0 Datatypes
> Affects Versions: 2.11.0
> Reporter: Tobin Stelling
> Attachments: XERCESJ-1591.diff
>
>
> This ticket is a request to incorporate the fix for XERCESJ-1591 into the
> 2.12.0 release of Xerces. Please refer to XERCESJ-1591 for detailed
> information about the bug and its fix.
> Attached is a svn generated patch that can be applied by entering trunk/ and
> running "svn patch <name>." The patch includes the fix currently checked into
> the xml-schema-1.1-dev branch (r1396551) as well as a new test. The test is
> in a new package under tests/ (schema.redefine). There might be a more
> appropriate place for it. The test walks through the example described in
> XERCESJ-1591 and asserts the correct error is returned by the parser (i.e.,
> that the ID attribute is required for element 'el').
> I'm submitting this ticket at the behest of David Costanzo who has already
> contacted the Xerces group regarding this bug.
> I also believe https://www.w3.org/TR/xmlschema11-1/#modify-schema, "This
> mechanism is intended to provide a declarative and modular approach to schema
> modification, with functionality no different except in scope from what would
> be achieved by wholesale text copying and redefinition by editing" shows that
> this is a bug.
