[x3d-public] Don, XSLT protoexpander?

[Don Brutzman]

BLUF: write javascript that uses a ProtoDeclare as a cookie-cutter macro design for stomping out new scene subgraphs.  A prototype... expander.

Multiple open-source proto implementations exist.  At first it can be hard driving in fog - but it gets a lot easier when you can follow someone else's tail lights.

The code patterns in XSLT are verbose (constructing strings and walking trees) in ways that don't match how any javascript implementation would go about doing things.  I further doubt that they want to include an XSLT engine in X3DOM, or depend on inconsistent browser implementations.


  Then there would be less code to download?  It would be worth seeing if there's a good product for XSLT 2.0 in the browser.
