xmlhack: VoiceXML 2.0 published - with patent issues

The W3C has published an initial draft of VoiceXML 2.0, along with a list of intellectual property issues.

VoiceXML 2.0 contains a number of changes from VoiceXML 1.0 including a new log element, the obsolescence of the dtmf, emp, div, pros, and sayas elements, as well as many changes to other elements and clarifications.

There are two layers of intellectual property issues with this draft. The first, a trademark issue, appears settled with a Memorandum of Understanding between the W3C and the VoiceXML Forum. The second is a collection of patent issues which have not been resolved pending the conclusion of the W3C's ongoing discussion of patent issues.
