   Please read the svg mailing list to understand the complexity of the
issue.

   The spec needs to be updated and until that happens I'm against
changing Batik's behavior only to have to change again when the Spec
is updated (causing problems for authors that need functionality around
this).

   You can also use an invisible 'blocker' element in addition to
the clip to intercept the unwanted events.

    I don't think this will work in Batik and I don't think it would
be an interoperable.  My above suggestion should work for any
implementation.
