Actually, Mozilla just uses CSSRule for the DOM representation of namespace 
rules (as in, instanceof CSSUnknownRule is false), but .type returns 
UNKNOWN_RULE for lack of anything better to return (since returning anything 
else would not be forward-compatible with spec revisions).  We do similar things 
for some other rules (e.g. @-moz-document).  Perhaps there should be a 
CUSTOM_RULE value to be returned in such cases?
