Hi Eric--

I myself don't know whether it should be considered a bug or a feature ;-)

In any event, my testing with Arbortext Epic 5.1 - which I think uses Xerxes-C - discloses the following:

• mixed="true" on xs:complexType element, but not on the xs:complexContent element that extends it to include the class attribute, as done in your refactored xsds, results in the loss of mixed content
• mixed="true" on the xs:complexType *and* on the xs:complexContent  elements restores mixed content
• mixed="true" on the xs:complexContent element *alone* also restores mixed content
  

And this concurs with the way I read the schema standard: xs:complexContent has a default mixed attribute value of "false." Nowhere do I find it documented that it should inherit the value from the xs:complexType element it modifies to override this default - nor does that seem a typical construct in xml standards. Usually, you'd at least need to set a value of "inherit" - or that would need to be the default.

In any event, putting setting mixed="true" on xs:complexContent elements where appropriate should fix the problem.

Hi Dana,

It looks like this one is a bug in the Xerces-C parser.  Xerces-J as well
as a few other parsers are returning the documents as valid.

One of two cases is happening.  Either  the anonymous type (complexType in
the element declaration) did not get the mixed="true" or  there is
something wrong with the schemas.  If it was a problem with the schema, ten
it should have returned the proper error.

That being said...I'll add the mixed="true" to the appropriate content
models as part of the design pattern. It may take a few days to make the
change and verify the changes.

Kind regards,
Eric

There appears to be a major bug in this refactoring, Eric.

It seems that the mixed=true attribute must be redeclared on the
complexContent elements used for the class attribute extension.

Otherwise mixed content is eliminated from elements that should have it.

At least, that's what happened in the commercial editor I used for testing.

      It doesn't affect validation of files, only the processing.
