What about the X3D format mentioned on 

Will this be the file format used for BlendXML?

I won't be able to help you develop BlendXML, but would be an user of 
it - and a very grateful one :)  We're working on a virtual reality 
(open source of course) that uses lots of XML for data 
representation. So far we are still in the progress of finding a 
suitable mesh format, but it certainly has to be in XML (at least for 
initial loading and network transportation). We certainly want to 
base the format on an open and accepted standard (X3D?) and it would 
be great if Blender would offer import/export capabilities for it.

We are also considering to use Blender itself inside the virtual 
reality as "mesh editor" for users to create new forms. I think the 
purely OpenGL based interface of Blender would allow for such an 
integration. [but that's another topic].

To sum it all up: we would be very grateful if Blender had the 
capability to "fully" import/export mesh data from/to a standardized 
XML format.

Thank you very much!!
