please comment on media-type registrations for MathML

[Paul Libbrecht <[e-mail]>]

Dear Media-types experts,

the last-call period for MathML3 has now launched and is set to end  
Nov 11th.
See the announce at: http://www.w3.org/mid/[e-mail]

In this specification draft, one can find three registrations for  
media-types related to MathML in the appendix B:
	http://www.w3.org/TR/2009/WD-MathML3-20090924/appendixb.html
They are copied below.

I would love comments on them until Nov 11th.

Paul


B.1 Media type for Generic MathML

This registration is for community review and will be submitted to the  
IESG for review, approval, and registration with IANA.

Type name: application
Subtype name: mathml+xml
Required parameters: none
Optional parameters: charset as per [RFC3023]
Encoding considerations: same as XML as specified in [RFC3023].
Security considerations: none
Interoperability considerations: entities with this media type also  
have the media type application/xml and may also have the media types  
application/presentation-mathml+xml or application/content-mathml+xml.
Published specification: MathML-3, draft at: http://www.w3.org/TR/MathML3/
Applications that use this media type: (todo)
Additional information
   Magic number(s): see [RFC3023]
   File extension(s): .mml
   Windows Clipboard Name: MathML
   Macintosh file type code(s) MML
   Macintosh Universal Type Identifier code: public.mathml conforming  
to public.xml
Person & email address to contact for further information: World Wide  
Web Consortium [e-mail]
Intended usage: COMMON
Restrictions on usage: None
Author and Change controller: The MathML specification is the product  
of the World Wide Web Consortium's Math Working Group. The W3C has  
change control over this specification.


B.2 Media type for Presentation MathML

This registration is for community review and will be submitted to the  
IESG for review, approval, and registration with IANA.

Type name: application
Subtype name: mathml-presentation+xml
Required parameters: none
Optional parameters: charset as per [RFC3023]
Encoding considerations: same as XML as specified in [RFC3023].
Security considerations: none
Interoperability considerations: This media type is a more specific  
type than application/mathml+xml. Hence any entity of this type is  
also of the type application/mathml+xml as well as application/xml. An  
agent offering this specific media type MUST also offer the  
application/mathml+xml media type. An agent delivering an entity of  
this media type SHOULD only do so if it knows the receiving party  
supports it, for example thanks to the Accept http header, and should  
otherwise deliver the more generic type.
Published specification: MathML-3, draft at: http://www.w3.org/TR/MathML3/
Applications that use this media type: (todo)
Additional information:
   Magic number(s): see [RFC3023]
   File extension(s): none
   Windows Clipboard Name: MathML Presentation
   Macintosh file type code(s) MMLp
   Macintosh Universal Type Identifier code:  
public.mathml.presentation conforming to public.mathml (described  
above) conforming to public.xml
Person & email address to contact for further information: World Wide  
Web Consortium [e-mail]
Intended usage: COMMON
Restrictions on usage: None

of the World Wide Web Consortium's Math Working Group. The W3C has  
change control over this specification.


B.3 Media type for Content MathML

This registration is for community review and will be submitted to the  
IESG for review, approval, and registration with IANA.

Type name: application
Subtype name: mathml-content+xml
Required parameters: none
Optional parameters: charset as per [RFC3023]
Encoding considerations: same as XML as specified in [RFC3023].
Security considerations: none
Interoperability considerations: This media type is a more specific  
type than application/mathml+xml. Hence any entity of this type is  
also of the type application/mathml+xml as well as application/xml. An  
agent offering this specific media type MUST also offer the  
application/mathml+xml media type. An agent delivering an entity of  
this media type SHOULD only do so if it knows the receiving party  
supports it, for example thanks to the Accept http header, and should  
otherwise deliver the more generic type.

   File extension(s): none
   Windows Clipboard Name: MathML Content
   Macintosh file type code(s): MMLc
