RE: [Speechsc] Problem with draft-6 RECOGNIZEcommandandtest/uri-listcontent type

Does this seem reasonable?

*******************************************************

text/grammar-ref-list MIME type registration 

IANA is requested to register the following MIME type according to the
process defined in RFC 2048. 

To: ietf-types@iana.org 
Subject: Registration of MIME media type text/grammar-ref-list

MIME media type name: text 

MIME subtype name: grammar-ref-list

Required parameters: 

None

Optional parameters: 

None 

Encoding considerations:  

Depending on the transfer protocol, a transfer encoding may be necessary
to deal with very long lines.  

Security considerations:  

This media type contains URIs which may represent references to external
resources.  As these resources are assumed to be speech recognition
grammars, similar considerations as for the media types
"application/srgs" and "application/srgs+xml" [1] apply.  

Interoperability considerations:  

We make the assumption that '>' is not a valid character in a URI
according to RFC2396.

Published specification:

The RECOGNIZE method of the MRCP protocol performs a recognition
operation that matches input against a set of grammars.  When matching
against more than one grammar, it is sometimes necessary to use
different weights for the individual grammars.  These weights are not a
property of the grammar resource itself but qualify the reference to
that grammar for the particular recognition operation initiated by the
RECOGNIZE method. 

The format of the proposed text/grammar-ref-list media type is as
follows:

  body        = *line
  line        = (comment | reference) CRLF
  comment     = "#" *<any CHAR excluding CR and LF>
  reference   = "<" uri ">" [parameters] [comment]
  parameters  = ":" parameter *(";" parameter)
  parameter   = name "=" value
  uri         = <same as 'URI-reference' production of RFC 2396>
  name        = <same as 'token' production of RFC2616>
  value       = <same as 'quoted-string' production of RFC2616> 

Note that MRCP currently only uses a 'weight' parameter, but there may
be the need for additional parameters in the future (even vendor
specific extensions).  Names of vendor specific parameters SHOULD start
with "x-".  

Example:

# Input for 'Form 1'
<http://example.com/grammars/field1.gram>  # weight 1.0 is default
<http://example.com/grammars/field2.gram>:weight="0.85"
<http://example.com/grammars/universals.gram>:weight="0.75"

Applications which use this media type:

Media Resource Control Protocol (MRCP)
