small comments on 2806bis-04

Hi Henning, folks,

Two comments for 2806bis-04.
Typos:
line 187: Clarification - should 'URI schemes' be 'URI scheme'?
similarly...
line 322: these URI schemes/this URI scheme/ ?
line 308: c/be /been/

Possibly add a sentence in the IANA considerations section to state:
'Any parameter that should be considered as mandatory should be 
prefixed by "m-" as described in section 5.3'.

Apart from that, I for one think it's fine.
I can read it, can understand how to test it, and the URI syntax is 
much cleaner.

(Now we can complicate it with 'tel:' URI parameter drafts :).

all the best,
   Lawrence
