[x3d-public] [x3dom-developers] [X3D-Public] Prototype

[Alan Hudson]

Not too be a hater but I don't think its a good idea to include PROTO's
into X3DOM.  The VRML/X3D proto spec + scripting interactions is very hard
to get cross platform.  I spent many years dealing with it and its just too
much work.  Personally I'd rather see that development time spent elsewhere
improving X3DOM.  It's very helpful to be able to define your own
vocabulary but as it stands PROTO's are not a proven cross platform way to
do it.  Maybe the other web native routes will have better luck.
