Please add an example such as this one:

Then explain how to use the Selectors API to select only the svg
'font' elements and how to select only the svg font elements that
have a prefix on the element.
As Boris explained, and as I'm sure you're well aware, it is not
possible to distinguish between elements with the same local name
without using namespaces. I cannot demonstrate the impossible and
have not included the example in the spec.
The SVG WG disagrees with this reasoning. People will run into this
problem, and it seems appropriate to give an example and to show how
to work around the lack of namespace-aware selectors. Note that even
if it's not possible to distinguish between the elements using
Selectors API alone, the result can be filtered e.g using DOM Core
methods to give a meaningful result. Another workaround could be to
pass a descendant combinator selector such as "svg font" to check the
the <font> element has an <svg> element ancestor, this would cover
many of the use-cases.
I will reconsider this issue shortly.
Erik provided me with demo to base the example on. I have simplified it
to illustrate the relevant technique and included the example within the
spec. You may review the changes in the latest editor's draft.

I believe this was the last issue from the SVG WG I needed to resolve.
Please let me know if you are satisfied with this response, and my
previous resolutions for other issues.
