notes on conneg-feature-hash-02

Hi all.
I have also read conneg-feature-hash-02...

sect. 3.2 : I am not sure what happens if we have an URI (either 
direct or dereferenced through a hash) and some explicit feature.
My personal logic will say that the latter overrides the "defaults"
provided, but I am not sure about it and I think that some word could
clarify the issue.

as for the vexata quaestio about direct URL appearance, I still think
that it could be left. It's true that we have the risk that the 
feature set is changed without notice, but in practice what would 
happen if you find that the URI does not have the correct hash?
I'd just write that systems MUST support the hashed form and MAY support
the bare one. 

ciao, .mau.
