Martin for the review. Sorry about the version mix up. For a diff 
between the version 6 and 7:

Please see comments inline.

In the correct version -07 this is now changed to:

    Encoding considerations:

       This media type is framed and binary, see section 4.8 in[I-

Okay, we can fix this. I haven't been that hard on this due to how the 
registry is currently structured. If one goes to IANA the reference 
points to the whole RFC. Thus one get both the template and the complete 
document in which it is included. But I will ask the author to fix this 
when the WGLC is over.

As the media type template is part of the actual specification, we 
define the parameters fully within the template. I don't see any gain by 
moving them outside of the template, simply more hassle for the authors.
