[x3d-public] Proposal: expressions

[Yves Piguet]

Validation for syntax and type checking could be done easily, at least more easily than scripts (the expression syntax I propose is way simpler than JavaScript). The main advantage I see in expressions is simplification, not enabling applications which weren't feasible before. Event utilities, like interpolators, can replace scripts in some cases, but require more nodes and routes.

Mainly declined, I believe, because to do the thing could possibly impair authortime and runtime validation steps. Also, the X3D event utilities were born due to some of the considerations you describe.
