+ *Random notes: 
+ *CSS core syntax vs CSS level 2 syntax
+ *=====================================
+ *
+ *One must keep in mind
+ *that css UA must comply with two syntaxes.
+ *
+ *1/the specific syntax that defines the css language
+ *for a given level of specification (e.g css2 syntax
+ *defined in appendix D.1 of the css2 spec)
+ *
+ *2/the core (general) syntax that is there to allow
+ *UAs to parse style sheets written in levels of CSS that
+ *didn't exist at the time the UAs were created.
+ *
+ *the name  of parsing functions (or methods) contained in this  file
+ *follows the following scheme: cr_parser_parse_<production_name> (...) ;
+ *where <production_name> is the name 
+ *of a production of the css2 language.
+ *When a given production is 
+ *defined by the css2 level grammar *and* by the
+ *css core syntax, there will be two functions to parse that production:
+ *one will parse the production defined by the css2 level grammar and the
+ *other will parse the production defined by the css core grammar.
+ *The css2 level grammar related parsing function will be called:
+ *cr_parser_parse_<production_name> (...) ;
+ *Then css core grammar related parsing function will be called:
+ *cr_parser_parse_<production_name>_core (...) ;
+ *
+ *If a production is defined only by the css core grammar, then
+ *it will be named:
+ *cr_parser_parse_<production_name>_core (...) ;
