after looking at this again I am thinking you could also say:

any= (attribute * - w:* { text }
   | text
   | anyElement)*

anyElement =  element * - w:* { any }


"-w:*" (assuming that the "w" prefix is bound to the widgets namespace) 
means that you exclude native widgets markup from the "any" defintions. 
That is just a suggestion, no need to handle this as a formal comments.
