[erratum xforms11] appearance attribute should allow a list, right?!?

I had long ago thought that the appearance attribute would allow a space 
separated list of names, rather like the CSS class attribute.
Recently tried to use that capability to express a new feature, only to 
have my developers come back to me with the information that neither 
schema nor spec supports this.
You get one of minimal, compact, full or a *single* QNameButNotNCName.
Isn't anybody else out there using space-separated list already?
I think this is an oversight that should be fixed by an erratum.

A particular use case I have is that I would like to say appearance 
minimal on a select1 to get a dropdown, but I would also like to control 
whether the selected item's label or value shows in the face of the widget 
when the dropdown list is released.  The default case is to show the label 
of course, but in densely packed layouts, the more compressed value can be 
preferred.
