Hi Dieter,

Ok so according to you, there's only one; either viewContext or
virtualViewContext.  That's fine with me.  I think it should be called
'viewContext' even if it is expressed in NVDC.  virtualViewContext is
confusing. Besides, we have that section in the spec which explains
that NVDC coords are used in the WebCGM DOM.

I can wait a bit, but if nobody can justify having both of them, I
suggest that we drop one (virtualViewContext).

Regards,
