I certainly don't want to do anything that would make us seem like bad guys..  I'm only interested in understanding the practical benefit of registering these things -- so I'm not opposed to the registration; I'd just like to understand the ramifications of us doing this.  I spent time earlier today on the IANA web site, and registration seems pretty straight-forward.  There were some questions for which I didn't have immediate answers for, but nothing seemed insurmountable.  One of the biggest questions is who should register these types?

Regarding the HTTP or MIME content-field, I'm not sure.  I was hoping someone with more knowledge could make a recommendation on this front.

Regarding their usage, I believe it is limited to the [Content_Types].xml part.  That said, I'd want to go through the spec again.  I recall there might have been a BRM issue or two regarding media where a change was considered to make this information more local to the XML itself.  I'd need to look into this, unless someone knows off-hand?

I would argue that it is our obligation to register OOXML media types.
ODF people have registered their media types.  The media types for XML are registered at IANA, and the media type for RELAX NG compact syntax is also registered (I was involved in both).  I do not want my working group to ignore best practices of Internet.  Now, people can rightly claim that we are bad guys and ODF people are good guys.

Since these media types belong to the vendor tree (as opposed to the standard tree), it should not be difficult to register these media types.  We only have to send some e-mails to the ietf-types mailing list.
More about this, see http://tools.ietf.org/html/rfc4288

I also think that 29500 should provide some more information about these media types.  Such information should cover parameters at least.

Are the media types listed in OOXML intended to be used in the HTTP or MIME content-field?  Or, are these media types used only in [Content_Types].xml?
If they are used only in [Content_Types].xml, I do not think we need parameters for these media types.
