Chair's report of the Voice Browser Working Group face-to-face meeting 
in Oslo, Norway, September 20-23, 2006

We reviewed the latest internal version of SCXML. We agreed to introduce 
an <anchor> element. Each time an <anchor> element is encountered during 
the processing of a SCXML specification, a snapshot of the database is 
placed onto a stack. Users may revert to earlier states by popping 
snapshots off of this stack. Torbjoern Lager from the Linguistics 
department of Goeteborg University presented an overview of his Synergy 
SCXML implementation [http://www.ling.gu.se/~lager/Labs/SCXML-Lab 
<http://www.ling.gu.se/%7Elager/Labs/SCXML-Lab> 
<http://www.ling.gu.se/%7Elager/Labs/SCXML-Lab> ] and discussed 
suggestions for enhancing the SCXML Language.

We reviewed and revised an internal draft of requirements for Speaker 
Identification and Verification for VoiceXML 3.0 based on the work of 
our sister committee, VoiceXML Forum's Biometric Committee 
[http://www.voicexml.org/resources/biometrics.html ].

We agreed to publish the power point files used during the SpeechTEK 
Conference tutorial "Sneak Peek at VoiceXML 3.0." These files will be 
available on the voice browser working group website 
(http://www.w3.org/Voice/) in a few days.  They represent a snapshot of 
our thinking for VoiceXML 3.0, and are subject to change without notice 
as we proceed with defining VoiceXML 3.0.

We reviewed and revised an internal draft of updated requirements for 
VoiceXML 3.0. We spent several hours reviewing "semantic models" of key 
VoiceXML 3.0 modules. We believe by working out the semantics of key 
modules before updating the VoiceXML 2.0 syntax and specifying 
additional VoiceXML 3.0 syntax, the modules will be well-defined and 
easier to integrate into a cohesive VoiceXML 3.0 language.

Thanks to Opera for providing facilities and refreshments, as well as 
the sun shining weather in Oslo. Our next face-to-face is scheduled for 
Boston on January 22-24, 2007.

Jim Larson and Scott McGlashan,
Co-chairs, Voice Browser Working Group
