To achieve this I had sightly modified libcroco - 0.6.0 - to be used in
CSSED as CSS validator, just making the error structure public and
modifying the SAC error handler so it's called with a line number.

The error stack is available at the end of parsing - throught an added
function  cr_parser_get_error_stack() - so you can get it to show those
errors to the user if something goes wrong.

The error stack is cleaned on parser's destroy.

Modified files:
cr_parser.c 
cr-tknzr.h
cr-tknzr.c
cr-doc-handler.c
cr-doc-handler.h

Implementation:

rev=1.14&view=markup

Unfortunately as it's modified it's no libcroco anymore ...
