This section has already been copied to Selectors 4 (and has been for awhile, actually), so should be removed here and replaced with references to Selectors 4. http://www.w3.org/TR/selectors4/#the-scope-pseudo If there's anything that needs to be fixed in Selectors 4 for this to be viable, then let us know and we'll fix it. :) http://www.w3.org/TR/selectors-api2/#grammar Tab just updated the grammar productions in Selectors 4 and defined some terms, so this section shouldn't need to define anything, just reference Selectors 4. http://dev.w3.org/csswg/selectors4/#grammar http://www.w3.org/TR/selectors-api2/#processing-selectors We also added the algorithm for absolutizing a relative selector to the Selectors 4 spec, so you can reference "scope-relative selectors", as defined here: http://dev.w3.org/csswg/selectors4/#scoping Please let us know if there are any errors. We'll try to publish a new WD soon with the updated definitions. ~fantasai + TJ
