IANA Media Types

Hello All,

I am pondering the choice of the media-type tree referent in [1], Section
4.3

Does anyone know why the media type tree is hosted at www.isi.edu (or if
this isn't "the" tree, why isn't it at www.iana.org, or something similar).
I am just wondering about the history of this. Further, these media type
designations are the same ones referred to in the DSig spec as used in the
"MimeType" attribute for the <Object> element. The values suggested here are
the bare media types names without the fully qualified URI shown in the XML
Encryption specification.

This seems odd, is there a compelling reason to have these be different
between the specifications? With anticipated use of both of these
technologies together, this just seems weird.

Phill,

For c14n, John Boyer had included the characters as close as possible in a 
comment with each example. We could do that, but I'm most interested in a 
tarball of examples with pre/post.

The white space is the same as C14N.

I'm not sure what you mean by notation. Literal octets and their digests 
seems to work well.
