nl_tokens: A bit hacky way to identify invalid CSS property definition : when user starts writing new abbreviation in CSS rule he actually creates invalid CSS property definition and this method tries to identify such abbreviation and prevent it from being added to CSS edit tree
pl_tokens: function isValidIdentifier ( <mask> ) { //		return true; var tokens = it . tokens ; for ( var i = it . _i + 1 , il = tokens . length ; i < il ; i ++ ) { if ( tokens [ i ] . type == ':' ) return true ; if ( tokens [ i ] . type == 'identifier' || tokens [ i ] . type == 'line' ) return false ; } return false ; }
