I think checking values explicitly is preferable to encoding them in
the syntax, since it gives you a chance to provide meaningful
errors. If you rely on the parser all you'll get is a generic "syntax
error" with no clue to what you did wrong.

WIDL: Add missing ignore attribute. Check for inapplicable attributes in typedef.

I think it is still possible to implement meaningful error messages. A 
good overview of  how this can be done is here: 
http://www.cs.nmsu.edu/~jeffery/merr.html.
Anyway, if you disagree, I will resend patch with explicit error check.
