Dec3D essentials

Dear all,

I've attached a document on the essentials of Dec3D.

In this document we tried to extract the key concepts of DOM-based 
declarative 3D as aimed by the W3C Community Group "Declarative 3D for 
the Web Architecture". Of course most of the concepts can be found in 
XML3D, some are planned for a future version of XML3D. Thus it's also a 
description of the lessons learned over the last years. On the other 
hand, the concepts are independent from the implementation and many 
concepts can also be found in X3DOM, either through its foundation X3D, 
but in many cases through the X3DOM-specific extensions that are not (or 
not yet) part of X3D.

This extraction must not be understood as manifest, but should server as 
a basis for discussion on a common "Dec3D" proposal. For this proposal, 
we should focus on the core functionality and concepts to increase the 
chance to make progress with our efforts. Agreeing on the essential 
concepts means that we can
.    incrementally refine each of the concepts
.    show up implementation alternatives
.    document why we've chosen this and not another option

Some points are not written very well because I wanted to have it out 
until the call tomorrow, but as I said, it's just a basis.

I hope, this will gain a momentum in the technical discussion in this 
group that should in parallel to the documentation of use-cases and 
requirements.

Best,
   Kristian
