[MathML3-last-call] media-types mentioned in encoding attributes

[polx]

Hello all,

MathML3 now define three media-types in the appendix B, this is the  
objective of another mail I will send to ietf-types. My objective is  
to discuss the encoding attribute values within examples.

Since MathML3, the annotation and annotation-xml elements carry the  
encoding attribute with the following recommended content:
1.- MathML-Presentation
2.- MathML-Content
3.- MathML
4.- the media-type of the annotation
5.- some text value you expect someone will recognize

If you look at the specification we have the following example values;  
I note that there are spurious occurrences of versions of 1, 2, and 3  
with a different casing which we should clean. Aside of 1, 2, and 3  
there are:

- well known media-types: image/png, text/plain, application/xhtml
+xml, image/tiff, image/svg+xml. No issues here.

- not yet standardized media-types:

--  application/openmath+xml: should probably be done by the OpenMath  
society one day, this follows directly RFC-3023 so there's no big  
debate here

-- application/x-maple: is justified by some documentation pages on  
MapleSoft's documentation and a private email exchange with Andrew  
Smith of MapleSoft. This is done for the sake of an "unregistered  
media type".

-- application/mathematica has been requested to change by Jason  
Harris of Wolfram Research to
    application/vnd.wolfram.mathematica
in the mail I reproduce below. I hereby propose to perform this change.

- non-standardized string: TeX, For this type, I have to say, there is  
no standard and it seems impossible to safely define one. We could  
replace it by application/x-tex which is what the Apache server  
delivers for a .tex file. On this point, I request suggestions.

thank you in advance for your comments.

Hello everybody,
I would be interested in knowing the current status of the MathML 3
standard.
I work with MathML 2 for several years and wonder when I will have to switch
to the new version.
Is it the right time?

Thank you in advance for your advices!

as indicated in the subject line it's at "last call". This, in the W3C
process, is the time for people to make comments on what is planned to be
a final feature complete draft.

The next stage is "candidate recommendation", hopefully later this year,
which is accompanied by a "call for implementation" at which point
implementors are encouraged to implement the new features, report
results of the test suite etc.

After that is "proposed recommendation" and then finally
"recommendation".

It depends how you work with mathml.

As an author of course you are constrained by the mathml system that
you use, for example the public versions of mathplayer and firefox
currently work with mathml2. However now is a good time to start looking
at and commenting on the new features.

As an implementor now is a good time to start implementing the new
features, as the best way to make detailed comments on the spec is to
implement it, and this last call period, and the following candidate
recommendation period are the times to get in any last minute changes
suggested by implementation experience.
