Correction:
Newlines shouldn't be ignored.
The title should just be shown correct with the newlines.
Will attach screenshot of Mozilla and IE handling the attached testcase.

Happens with the "MIT" link at the bottom of http://www.w3.org/DOM/ as well.

cc'ing Hixie to make sure we're right about what the the correct behavior is.

Comment 5

[Hixie (not reading bugmail)]

Correct behaviour is to treat newlines as whitespace (and trim leading and 
trailing whitespace) per HTML4 and SGML. I don't know what we should do in
XML. This is a parser-level requirement per the spec. Check Bugzilla's INVALID,
WONTFIX and FIXED bugs with the words "newline" and "attribute" in the 
description fields for bugs similar to this one where this has been discussed 
to death.

But what should we do for 
 ?  (What do we do now?)  In a DOM where we want
to preserve all whitespace for editing, etc. (perhaps this is contrary to SGML,
though, but...), how should we behave?  (How should we handle 'content: attr(X);
white-space: pre'?)

Exactly the same thing we do for ordinary CRs/LFs. There are *no* difference in:

<CR>
&#x000d;
&#013;

They're *exactly* the same characters (they're canonically equivalent).

This bug has been marked "future" because the original netscape engineer working 
on this is over-burdened. If you feel this is an error, that you or another
known resource will be working on this bug,or if it blocks your work in some way 
-- please attach your concern to the bug for reconsideration -----
