I have downloaded CSSParser and hoped(or hope even) to use it to 'poperly'validate CSS (CSS 3).
I currently use the Jigsaw web service and interpret the SOAP responses, but what I really want is a library to embed in my code (which is in fact an Eclipse plugin in this case) rather than use a web service.
The trouble is though that it doesn't seem that CSSParser validates beyond basic syntactical constructs.
For example, if I have a rule cursor: hand , then Jigsaw tells me this is incorrect (similarly other inappropriate values for rules), and also gives warnings for unknown or browser specific rule names. In contrast, CSSParser seems to be letting these through without even a warning.
Is this expected behavior or am I missing something (e.g. a configuration or a dependency jar)?
