Comment 1 Mathias Bynens 2011-06-11 07:02:13 UTC 
All kinds of whitespace characters are disallowed in attribute values. For example, these two will have the exact same result:

    <!-- spaces -->
    <p id=foo  bar>
    <!-- tabs -->
    <p id=foo			bar>

Obviously, `bar` will be considered as a separate attribute, and won’t be part of the @id attribute value.
Comment 2 Mathias Bynens 2011-06-12 17:03:57 UTC 
> The value, along with the = character, can be omitted altogether if the value is the empty string.

I believe “can” is supposed to be “should” here. <p id=> isn’t conformant.
Comment 3 Mathias Bynens 2011-06-12 17:06:34 UTC 
Also, perhaps a link to http://www.whatwg.org/specs/web-apps/current-work/multipage/syntax.html#unquoted somewhere from this section would be useful.

Status: Partially Accepted
Change Description: see diff given below
Rationale: 

Please file only one issue per bug.

For comment 0: I've changed it to "space characters" which has a more precise defined meaning. However, note that this entire section is very vague and isn't really trying to be precise. It's just an introduction. If someone wants the exact rules they should look at the actual rules.

For comment 1: No actionable feedback.

For comment 2: No, this is not a normative section.

For comment 3: There is already a link to that section in the very sentence quoted in comment 0.
Comment 6 contributor 2011-08-19 02:59:10 UTC 
Checked in as WHATWG revision r6514.
Check-in comment: Add a cross-ref here to make it easier to see what is meant.
