If it is easy it would be nice to know in what line the CSS error occurs.

Tue May 3 18:08:54 2011: C:\Documents and Settings\Albright\My Documents\My Princess\css\Biblica.en.NIV.2011.css: warning: failed to parse all CSS rules

Oxygen is NOT very helpful as they don't know about all the rules Prince uses --- especially the Prince extensions.

I've added this to the roadmap for 8.1, as it would be convenient when working with large style sheets.

Prince 11 has an all new CSS parser with improved conformance to the specification and... syntax validation! At last. Although line numbers are still inaccurate for <style> elements, unfortunately. Hopefully we can fix that next.
