Felix,

Thank you for your comments on SRGS. I'm sorry for the long delay in
replying.

(This is the reply from the Voice Browser Working Group to the
following mail:
http://lists.w3.org/Archives/Public/www-voice/2002OctDec/0045.html)

Your mail contains two comments on the ABNF format. The first one
regards delimiters of 'meta' and 'http-equiv' strings, the second
one tag delimiters.

1. Delimiters of 'meta' and 'http-equiv' strings.
Support for escape sequences was not added to the ABNF format because
this would make the syntax more complex while there seem to be no
important use cases for it.
There are several issues regarding the conversion to and from ABNF Form
and XML Form. Section 1.3 of SRGS
(http://www.w3.org/TR/speech-grammar/#S1.3)
contains a list of these issues and states that ABNF Form and XML Form
are specified to ensure that the two representations are semantically
mappable. This means that the semantic performance of a grammar does
not change when it is converted to and from ABNF and XML.
The fact that quote characters in 'meta' and 'http-equiv' strings
cannot be escaped does not affect the semantic performance.

2. Tag Delimiters.
This issue has already been discussed during the Last Call period of
SRGS. Further details can be found in the disposition of comments
http://www.w3.org/2002/06/speech-grammar-comments.html,
specifically in the section on GC09-14
http://www.w3.org/2002/06/speech-grammar-comments.html#GC09-14.

If you have any further questions, please feel free to ask.

Regards,
Stefan Krause (ScanSoft)
