WSDL 1.2 draft editorial questions

I'm editing and hence have questions ..

Currently <include> and <import> do not allow extensibility. Was
that intentional?? I think that's just an editorial glitch which
should be fixed.

In the current draft, when say element foo has an attribute bar,
it says "a bar AII ..." and doesn't explicitly say "a REQUIRED
bar AII". For optional attributes it does say optional. Shouldn't
it say REQUIRED explicitly??
