I agree that there is nothing wrong with it.  Implementations need to 
make sure that common styling rules will not cause ill-effects to the 
form that is displayed by their processors.  We fixed two bugs where 
styling rules were screwing us up just this past week :-)

My point exactly.  Here is one example where even if something exists in 
the spec to spell out how to style xf:items and an author adds such 
rules to his/her form, a processor could still ignore the styling rule 
and yet be fully compliant.  A form author can only expect a processor 
to honor the styling rule if it makes sense in the context of the 
widget(s) that the processor chooses to use to render the xforms control.

So in the end, the results that the form author experiences will be 
processor dependent.  Though should such rules make their way in the 
spec, it is a good way to ensure that processors that DO want to apply 
styles to xf:items in certain appearances or in some data type bindings 
will have enough information to guide them in doing so.

probably xf:choices, too.
