Hi Philippe,
I've done a detailed review of the 3 registrations. application/xslt+xml
and application/xquery+xml look fine to me (I might have some non
blocking nits I report separately). I have some further comments
regarding application/xquery, I am sorry that I haven't spotted them
earlier.

So, how do you want to proceed?
I suggest that I separate IESG review of application/xslt+xml, from
review of application/xquery+xml and application/xquery. This way
application/xslt+xml can be approved on September 24th and the remaining
2 can be dealt at a later date.

In particular:

1).
<http://www.w3.org/TR/2009/PER-xquery-20090421/#id-registration-of-mime-type>
is using own order of sections (and sometimes uses different section
names) from the template prescribed in Section 10 of RFC 4288. I thought
information about Magic numbers is missing, but I finally found section
"G.4 Recognizing XQuery Files", which covers that. In the future, I
would ask W3C to use the correct template, as it makes checking
registrations easier.

2).

Is there any good reason for allowing Latin-1? IETF pretty much settled
on only using US-ASCII, UTF-8 (and rarely UTF-16).

I may have used an outdated template - XQuery was either the first or one
of the first specs to use this new combined process.

To the best of my memory it was for in response to a comment regarding
HTTP cpmpatibility, but, there is also no good reason to forbid it at
this point, with over 50 XQuery implementations in the field.

For XQuery 1.1 we could possibly disallow Latin-1, but I don't think
we'd gain anything now.  If we were still in 2005, we'd be in a
position to change such things, and I think do a better job.
Removing it could only hurt interop now I think.

Thanks for the comments!

I think
http://www.w3.org/TR/2009/PER-xquery-20090421/#dt-encoding-declaration
makes it clear that XQuery documents can be in very much any encoding.
So the mention of Latin-1 in the Mime type registration is just an
example. As such, it can stay in the registration template or be removed
without any effect on interoperability.

[charset expert reviewer hat on]
However, there is no 'charset' "Latin-1" registered at
http://www.iana.org/assignments/character-sets. So I strongly suggest to
replace it with ISO-8859-1, or leave it out.
[hat off]

Regards,    Martin.

If this is done for backward compatibility, this is Ok with me.

Please address Martin's concern about Latin-1 not being registered.

I think we can make that change :-)

Thanks for the comments!

I've filed an issue/bug against the document [1].

Today the XQuery WG agred to make that change , both for
XQuery 1.1 (in development) and as an errata to XQuery 1.0.

Public record of decision:

Thanks.
Let me know when the document is updated with new text and I will ask
IESG to review the registration.
