I think the global xf:version appearing on the root element of the 
document would not be just an authoring hint.

An XForms processor already has to scan the whole document anyway to find 
its models and UI controls, and indeed the other global attributes.

If it doesn't appear, then versioning by the local attribute on model 
would take over (and the default of 1.0 is already specified),

But if xf:version appears, then it should provide the version and a 
version exception should occur if it conflicts with the version numbering 
provided by the local attribute.

Re: XForms document versioning








My own preference is to have a version attribute (re: the TAG
discussion).

One possibility -- since xf:version is an author hint -- and
given that 1.0 didn't explicitly use it -- would be to default
xf:version to 1.0 when missing.
