Circular paths

In the following:

<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" >
<path d=" M 200,300 a 100,100 0 1 1 .0001 0 z " fill="white" stroke="black" stroke-width="3" />
<path d=" M 400,300 a 100,100 0 1 1 .00001 0 z " fill="white" stroke="black" stroke-width="3" />
</svg>

Opera, Chrome, IE+ASV all show one circle. Firefox shows two. I would prefer to see two.

It would be nice if even 
<path d=" M 400,300 a 100,100 0 1 1 epsilon 0 z " fill="white" stroke="black" stroke-width="3" />

for the limiting case when epsilon=0.

cheers
