---------------------------------------------
Assignee: Khaled Noaman
Khaled, since you've been keeping up with the XML Schema 1.1 dev more than I
have can you take a look at this one?
Some observations / questions from my quick review:
1) fisAtomicValueValid is being set to false when
XSTypeHelper.isAtomicValueValidForAnUnion() returns true. That seems backwards.
2) fisAtomicValueValid isn't being initialized in reset(). Might be a bug.
3) Why are we calling isAtomicValueValidForAnUnion() anyway? We've just
validated the value and seems that method calls the DVs a second time.
4) Why are we trying to call isAtomicValueValidForAnUnion() for the lexical
form of the default value? Note that's where the NPE is. We're passing in null
right now, but even if we were to pass the lexical value that was in the schema
that doesn't seem right (e.g. trying to revalidate a defaulted QName value from
its lexical form wouldn't work).

> Project: Xerces2-J
> Issue Type: Bug
> Components: XML Schema 1.1 Structures
> Affects Versions: 2.11.0
> Environment: Java version: 1.6.0_23
> Java home: C:\Program Files\Java\jdk1.6.0_23\jre
> Default locale: en_US, platform encoding: Cp1252

> Priority: Blocker
>
> The following is a regression from 2.10 because our unit tests run OK with
> 2.10 and blow up with 2.11.
