html code:
<label for="foo">Label Text</label>

The W3C DOM states that the 'for' attribute should be 'htmlFor' in the DOM. 
This is to avoid conflict with the javascript keyword 'for'.


JAVASCRIPT CODE:
var x = labelElement.GetAttribute('htmlFor');

EXPECTED:
x should be the 'for' attribute of the labelElement object.

RESULTS:
x is null.

Note: labelElement.GetAttribute('for') does return the 'for' attribute - in fact
this return null.

Reproducible: Always
Steps to Reproduce:
1.  Open up testcase1.html (attached)
2.  Click through the input elements




Expected Results:  
The relevent label should be highlighted.

This bug is also present in Firefox 0.8 under Windows XP.

Attachment: Proof of concept - uses 'htmlFor'

Testcase1 shows sample code using getAttribute('htmlFor')

Attachment: Proof of concept - uses 'for' attribute

Testcase2 shows sample code using getAttribute('for').

This 'for' attribute is invalid (according to the W3C DOM) and therefore, the
code should not work.

That section in the DOM rec is about property attributes (see section 1.6.1),
HTML attributes exposed as properties on their elements. Try element.htmlFor.
