Hey Erik,

We created this particular XForm to give an example of what a user's 
experience is with XForms.  It is not, however, a good example of proper 
XForms authoring (as noted in the Disclaimer toward the top of the form 
source).  Due to a variety of limitations that currently exists in our 
XForms implementation, we could not achieve the table-type of layout 
that we desired in any other way.  When our next preview release comes 
out and we can achieve the desired layout in the 'proper' way, we'll 
update these samples and include new samples.

As far as bugs, there is nothing that says that a label MUST be 
contained in a form control, though that is often the case and is pretty 
much what it was designed for.  So the fact that a label will render 
outside of a form control is not a bug.

thanks,
