I will add that I have confused 'auto' with 'default' as in.


Default:

<ul>
<li>Item</li>
</ul>


Vertical margins with Auto:

<ul style="margin-top: auto; margin-top: auto;">
<li>Item</li>
</ul>


The former case will show the default vertical margins of the UL and the 
later should resolve 'auto' to '0' as per the spec.


http://www.w3.org/TR/CSS21/visudet.html#normal-block

If 'margin-top', or 'margin-bottom' are 'auto', their used value is 0.


It would help us all to see first hand some of the internal test that 
Arron has done.
