(Core :: CSS Parsing and Computation, defect, P3)

Description

[Björn Höhrmann]

According to http://www.w3.org/TR/REC-html40/types.html values of the ID 
Attribut cannot start with a number (e.g. ID=1 -> #1 { /* style */ } ).

According to http://www.w3.org/TR/REC-CSS1#forward-compatible-parsing such an 
illegal declaration must be ignored.

Tested on M13, win32 (NT 4 SP 4)

It may be an error in the CSS2 spec but for now IDs can start with a digit (not 
classes). See bug 18936 for the whole story, especially the comments from David

Yes.  See the grammar: http://www.w3.org/TR/REC-CSS2/grammar.html .  ID
selectors match the HASH production which is "#"{name}, where name is
{nmchar}+ (as opposed to ident, which is {nmstart}{nmchar}*)

I forgot to thank you for the excellent attached testcase. I wish we had more 
like these, it really makes the job much easier. Thanks-a-lot!
