I hope this program will fully follow W3Ds standards.
Please read the bug writing guidelines at http://www.mozilla.org/quality/bug-writing-guidelines.html and revise this bug accordingly. I will mark it INVALID within the week if I do not hear back from you.
w3c i mean
Additional Info: Communicator didn't fully follow w3c's CSS style sheet standard because some of the attributes didn't work.
The aim is full support for W3C CSS1 using CSS2 interpretations of those CSS elements. Any missing features or bugs with CSS support should be filed separately, preferably checking first to see whether they're already in this database, and one bug per issue. As it stands this could mean anything.
There's lots of work on W3C standards support. As matty said, if you know of specific unknown W3C noncompliance issues, please write them up as independent issues. Most of them are already known, so I'd suggest checking before writing any up. Resolving as INVALID for cpratt who is out sick.
