Description

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.

---------XML Document----------------
<BookStore xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="schema.xsd">
<Book lang="fr">
<TitleFr></TitleFr>
<Author>
<NameFr></NameFr>
</Author>
</Book>
