Hi,

I've got a question about UI binding to other XML vocabularies.  Section 
7.5.4 of the spec mentions it should be possible and even gives an 
example.  The example shows:

<html:input type="text" name="..." xforms:bind="fn"/>

What I'd like to know is, is this a node-set bind or a single node bind? 
  How is the processor supposed to know which it is?  After all, it is 
very conceivable that both should be possible.  For example, why 
couldn't an html:optgroup with @bind automatically generate html:options 
(one for each node in the bound nodeset) similar to how xf:itemset 
automatically generates xf:items?

While I could see that it might be up to the CDF WG to define how an 
element of a particular host language with a bind will behave that has a 
binding attribute, I would think that it would be up to the XForms 
working group to define how to determine if the binding is a single node 
binding or a node-set binding.
