Getting the enclosing Document from a Type

Hello,

I'm using the substitute() method as explained in a previous thread:

> xmlObject = xmlObject.substitute(ClassADocument.type.getDocumentElementName(), ClassAType.type);

> I was just wondering if there is a way to retrieve ClassADocument.type
knowing ClassAType.type ? Or maybe using directly ClassAType ?

The case is that I have an evolving list of different ClassAType and it
would be great if I don't need to worry about hard-coding the
ClassAType/ClassADocument
relationship each time.

Thanks in advance for any help or hint.

Best regards.
