Many thanks for your comments. You may be interested in the recently published revision to the XForms specification which I believe addresses the points you raise: http://www.w3.org/TR/xforms/ (19 December 2000) On Wed, 20 Dec 2000, Evelyne Viegas wrote: > Here are some comments on the following working draft: > Natural Language Semantics Markup Language for the Speech Interface > Framework NL semantics markup (20 November 2000): > <http://www.w3.org/TR/nl-spec/> http://www.w3.org/TR/nl-spec/ > > The specification mentioned above seems to be fairly broadly defined so that > it could be extended to accommodate the needs of various semantic > interpreters, as mentioned in the following section of the specification: > "Extensibility: The specification should be extensible to accommodate > emerging and future capabilities of automatic speech recognizers (ASR's), > natural language interpreters, and voice browsers.
