That's a different take than I thought it meant (the docs that is). 
Makes sense tho, if true.  I thought from reading "one or more forms" in 
the docs I've seen, that it meant "allowing the input to be included in 
*all* of the forms mentioned in the attrib.

Something that should be tested by our OP here.

Of course the real problem is html 5 support.
