[Xvrml-schema-dev] drop of Alpha Schema and examples for review

[Jeff S. <je...@ar...>]

I have dropped version 0.32.09.00 alpha 
of the xVRML Schema and Schema documentation and modified examples
onto the Project server at:

  http://www.xvrml.net/currentAlpha/

the changes proposed in this version are primarily in the Shape node
and I need for people to review:

  http://www.xvrml.net/currentAlpha/docs/core.html#element_Shape

and to comment to <xvr...@li...>

inside the Shape.appearance is the last place that
semantics associated with Use needed to be fixed
as the current beta Schema would not allow
replacing *both* 
appearance.Material and appearance.Texture 
with Use nodes
and that is not our intent

thanksfully this appears to be the only place
that Use is broken

I have brought back some notation from VRML97
now that I remember why we needed it in the first place
to solve the problem

I reworked a bunch of example xwrl files
and placed them on the server too
to illustrate what effects the changes to the Schema
will have on xVRML world files...
it is because the changes **will** break existing content
that the version bumps to 0.32.09

the reworked examples may be found at:

  http://www.xvrml.net/currentAlpha/examples/

the file "appearanceCombos.xwrl" shows all permutations
of all the legal combinations of 2 which were intended:

  (material and texture) 
  (material and Use) 
  (Use and texture)
  (Use and Use)

Project team members: 

please insure that you are subscribed to 

  xvr...@li...

as that is where I would like the discussion to take place

this is the most straightforward route I can find
to insuring that the combinations and permutations
which we intend to be valid
are valid
while insuring the validation process 
relieves the application
of as much responsibility 
for insuring it is a good file
as is reasonable
