problem sentences in draft

In section 4:
"The User Agent must not categorically prohibit dispatch of unknown 
intent types."

The double negative means the UA must do something, but the spec does 
not say what.
This sentence needs to be removed or changed.
Possibly to something like:
"The User Agent maychoose to dispatch unknown intent types based on 
information not contained in this specification."

By the way, the word "categorically" adds an ambiguity: the UA must not 
categorically prohibit, but is it OK for the UA to (simply) prohibit ?


Also in section 4:

" The User Agent/must not/allow web pages the ability to discover 
passively which services..."

What it the meaning of "passively" in this context ?
This should be unambiguously explained IN the spec (not to me).

Best regards
