wrt "application/saml+xml" (draft-hodges-saml-mediatype-00)

Attached is the initial rev of an I-D seeking to register the MIME media type 
"application/saml+xml". Please review.

I've pinged the I-D editor to request a filename for the doc, I'll submit it to 
both the I-D editor and the SSTC doc repository once that's finalized (std 
procedure for I-Ds).

In concocting this draft, I've noted that MIME media type registrations aren't 
necessarily the simple little registration exercise I'd thought they were. They 
(the  denizens) may desire more content, e.g. sec 
considerations, in this doc. We'll see. Nominally, I think it's "good enough" 
as is, especially since the SAML spec sets have thorough sec considerations 
sections and I've referenced said spec sets carefully. Anyway, we'll see.

Also, I based this on a draft registration for application/rdf+xml. In that 
draft, Aaron Schwartz claimed an optional parameter of "charset", and indicated 
that the considerations thereof are the same as for "application/xml" (as 
documented in http://www.ietf.org/rfc/rfc3023.txt). Additionally, he did the 
same thing for the "encoding considerations", i.e. said they were the same as 
for "application/xml".  So, without excrutiating research, I did the same thing 
in this draft. fwiw/fyi.

anyway, lemme know whatcha think.

thanks,

ps: this is getting  done later than I'd hoped due to sick kid impacts this week.
