VoiceXML 2.1: VoiceXML 2.0 support

Dear Voice Browser Working Group,

  http://www.w3.org/TR/2005/CR-voicexml21-20050613/ notes that 

[...]
  Interpreters that support both VoiceXML 2.0 and VoiceXML 2.1
  must support the ability to transition from an application of
  one version to an application of another version.
[...]

This implies that VoiceXML 2.1 implementations are not required to
support VoiceXML 2.0 documents, it's however not clear why. Please
either change the document such that 2.1 implementations must also
support 2.0 documents or such that it is explained why VoiceXML
authors might find implementations that only support VoiceXML 2.1.

regards,
