Tim,
Firefox-only issues are usually caused by its XSLT engine not supporting
the namespace axis. A trick is necessary for XSLTForms to get the
namespaceURI from the prefix: adding some dummy attribute, such as
bf:dummy="dummy", at the document element should be enough. With this
trick, your test forms are working for me with Firefox too.
Subforms mechanism in XSLTForms is merging models and ignoring already
existing instances. Without any declared model, XSLTForms is actually
declaring a default one. For unit tests, it might be interesting to
declare the main models and the main instances used in the subform just
to be able to run it independently.
Thank you for your feedback!

Subject: Namespaces in subforms (Firefox)
To: Alain Couthures <[email protected]

Alain,
The "not well-formed" issue in Firefox seems to have been caused by an
external JavaScript library that I was using, so I'll have to
investigate that myself.
However, I did discover another issue in Firefox that may or may not
be a bug.
My understanding of subforms in XSLTForms, as Eric van der Vlist
explains it, is that "XSLTForms doesn’t isolate the models from the
master form and its subform and it is possible to access directly to
any instance of the master form from the subforms." By that token, it
should not be necessary to repeat instance data in a subform model, is
that correct? The subform controls can be bound directly to the
mainform instances.
A couple of basic tests seems to confirm that this is the case (using
your writers/books example). Test 1 works in Firefox, Chrome, and IE.
But if namespaced elements are used in the mainform instance, as in
Test 2, this pattern causes Firefox to fail. If the model element is
uncommented in Subform 2, then Firefox loads the subform correctly.
So, is a local model always necessary in the subform, or is this an
issue with Firefox? Tests are also attached.
Thanks again,
Tim
