Re: [Xsltforms-support] Fwd: Namespaces in subforms (Firefox)

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!
