Bjoern,
This is the SVG WG response to you're the thread that begins with:
   http://lists.w3.org/Archives/Public/www-svg/2005Apr/0234.html
And where your last response (copied below) was:
   http://lists.w3.org/Archives/Public/www-svg/2005May/0258.html

Thanks for your follow-on comments on this issue. We agree that unqualified event names belong in the XML Events namespace. We have reviewed the specification to make sure that it is clear that this is true. The latest draft now says the 'event' attribute can only accept a particular discrete set of event names (with a hyperlink to a section which provides the list of values), and then the referenced section now says that all of the events that are allowed are in the XML Events namespace. 

Please reply to this mail within two weeks if these changes do not
address your concerns.

Thanks

SVG WG

This does not satisfy me. Now that ev:listener has been added to SVG
Tiny 1.2, you would also need to say the algorithm for ev:listener's
event attribute. Looking at the draft I also note that it does not
discuss the event name in case of invalid and absent values for the
attribute, and I strongly object to ev:event="x" matching "x" events
in any namespace, it's guranteed that authors will use the simple
unprefixed forms and hence cause a lot of trouble using new and
custom events. Please define the things mentioned above and change
the algorithm to default to the XML Events namespace.
