Hi Randy,

Isn't the more important question what quality of standard it is? And how 
usable and informative people find it?

I am fairly comfortable with XSD schema or Relax NG (having explored its 
predecessor TREX a long time back) but I know lots of people who really 
struggle with XSD schema. If Relax NG is more useful, and helps readers to 
understand the SVG spec, isn't that a good thing?

Why is it being abandoned willy nilly by various

I don't think you can fairly use the term "willy nilly", since this is being 
discussed in a sensible, open, rational way.

It makes sense to me that a W3C WG uses the most appropriate tool for the 
job, wherever it was invented.

Which utilities did you have in mind?
