Re: [whatwg] Scripted querying of capabilities

[Dave Singer]

Pitching in here, I think it's OK if we want to go to a two-state 
answer -- but those answers are No and Maybe, not No and Yes.  There 
are, after all, vanishingly small numbers of mime types where I can 
be 'completely' (within reason) confident of a 'yes' answer.  On the 
other hand, given a mime type I simply don't recognize, or a codec I 
know I don't have, I can be confident of a No.

Documenting it as providing a No/Maybe indication, and that how 
positive the 'Maybe' is depends to a large extent on how precise the 
supplied mime type is, would be fine by me, I think.
