> In Chapter 2.1, it is stated (without further explanation):
> "This can be represented in the XForms model element, which in XHTML would
> contained within the head element".
> It seems to me that this is not a statement that can be made without
> qualification. It is not, as far as I am aware, true for XHTML 1.0.
> I suggest that consideration be given to adding a version number to the

> XHTML head element. Is there anything to prevent the xforms:model element
> being present in the body element but simply not be rendered?
