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

Test 1 (no namespaced instance elements)
