Mukul Gandhi commented on XERCESJ-1590:
---------------------------------------
I agree, that there seems to be a bug as you've given an appropriate example
for that. If you remove the following element from the schema which you've
provided, <xs:alternative type="enAuthorType"/> (within the element
declaration, <xs:element name="Author">) I can see that the needed
functionality becomes available.
Great to see that, Michael has volunteered to look at this issue.

> Key: XERCESJ-1590
> URL: https://issues.apache.org/jira/browse/XERCESJ-1590
> Project: Xerces2-J
> Issue Type: Bug
> Components: XML Schema 1.1 Structures
> Affects Versions: 2.11.0
> Reporter: Octavian Nadolu
> Assignee: Michael Glavassevich
> Priority: Trivial
>
> When I validate the following xml document with the associated schema, I get
> the error: cvc-complex-type.2.4.a: Invalid content was found starting with
> element 'NameFr'. One of '{NameEn}' is expected.
> There should be no error because the lang attribute is inheritable, and the
> Author element type should be frAuthorType.
> I tested on the xml-schema-1.1-dev branch.
