Both are intended to be normative, but the authoring format is RNG 
(converted to WXS). The RNG schema is recommended because it is more 
stringent than the WXS one, and thus guarantees better validation.

It's far from finished but it's getting there.

It also depends on usage types. I think that a lot of people that hand 
author schemata are switching or have switched to RNG. People that 
generate WXS through class-to-schema bindings and graphical tools 
probably use WXS more because it's what the tool outputs, even if in 
fact they probably don't care that much.

The fact that it's impossible even today to find two interoperable 
implementations of WXS is usually a good selling point for RNG.
