Description Eugene Villar 2003-06-03 09:04:27 UTC 
Similar to Bug 155. Both XML and HTML allow underscores in id atributes.

Line: 82 Context : #skip
Parse Error - #skip_nav {display: none;}
Comment 1 Sijtsche Smeman 2003-07-11 10:30:26 UTC 
Bug does only exist in online version, not in the CVS version anymore. 
Considered as fixed

Comment 3 Etan Wexler 2004-11-25 16:06:31 UTC 
HTML specifications, free to read online, have never allowed the underscore in
ID values.
Comment 4 Eugene Villar 2004-11-26 11:08:15 UTC 
According to HTML 4.01 specs, underscores are allowed:

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by 
any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons 
(":"), and periods (".").
Comment 5 Eugene Villar 2004-11-26 11:11:35 UTC 
Sorry, I forgot to include the relevant links to the specs:

http://www.w3.org/TR/REC-html40/struct/global.html#h-7.5.2
This shows that the id attribute is of type 'name' token.

http://www.w3.org/TR/REC-html40/types.html#type-name
This shows that name and id tokens can have underscores.
