Yes, I overlooked that part.  Thanks.

No problem, I know that you're busy.

That's fine as long as the user is handling the element as an
SVGPathElement explicitly.  I'm thinking of situations where the user is
treating the object as a DOM Element or DOM Node.  Say, for example, that
the user is stepping through the DOM tree (in this case, an SVGDOM tree)
using a treewalker or nodeiterator,  and they want to perform some
processing of attribute "d" on this particular node.  For the purposes of
a concrete example, assume that they want to serialize the DOM tree to
file.  To do so, they walk the tree serializing each node and that node's
attributes.  Now, what happens when they attempt to serialize an
SVGPathElement node?  Which list should be used as the "d" attribute? 
There are ways to code around this, but I think it might be useful to
consider adding some switch which allows the user to specify which list is
used by default in these sorts of situations.
