[css-selectors]

After reviewing the Grid module, I started reviewing some of the  
other modules. In the Selectors module, I found the example for  
section "6.6.3 The language pseudo-class :lang" which seems wrong.

Does the selector ':lang(fr-be)' match French and/or Belgian, or does  
it match the Belgian dialect of French? As I remember the language  
specification (possibly incorrectly), I believe it should be the  
latter. If my memory is correct, then the example in the  
specification needs to be fixed.

I checked the referenced document (RFC3066) and it seems my recall  
isn't totally wrong. If my memory is failing, would someone please  
point out where the correct information lies?

Thanks,

James Elmore
