Thanks Ray, I believe it is!

A schema listed there is available for requesting with the 
"&recordSchema=" parameter, yes? Cool, that's exactly what I was looking 
for.

Another question though. I note when looking up schemaInfo... I'm a bit 
confused by the "sort" attribute.  How could you sort by a schema? What 
is this attribute actually for?
