---------------------------------------
Hi Chris,
Thanks for reporting this issue.
I would agree that you have spotted a potential bug. For the test case you've
submitted with this bug report, your patch seems to work fine.
But your patch seems to produce a side effect (i.e it seems to break something
else within Xerces).
After I apply your patch, the result of the XSD 1.1 "schema test" s4_2_4si01s
get's inverted [1]. We've existing Xerces W3C XSD 1.1 (IBM) test results here,
http://wiki.apache.org/xerces/xmlschema11IBMTests (you may search this page for
the test s4_2_4si01s).
This test id (i.e s4_2_4si01s) seems to be refereed in this file,
http://dev.w3.org/cvsweb/XML/xml-schema-test-suite/2004-01-14/xmlschema2006-11-06/ibmMeta/cyclicRedefineIncludeImportOverride.testSet
(which you may inspect to study the affected test XSD file).
I believe, we must find way how to restore the functionality of the affected
test case [1], along with the needed fixes that you've proposed.
If you're willing to revisit your patch, to help restore the affected XSD 1.1
test [1], that would be great. In the meantime I would try to find answers at
my end.
Regards,
Mukul

> If, say, an element references its type and the element is lexically before
> the type then the type may fail to resolve if the type name contains
> whitespace. This will happen for all cross references as they are handled
> similarly. I'll attach a patch with a test and simple fix shortly.
