DJ>   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
DJ>   xsi:schemaLocation="http://www.w3.org/2001/svg">

Something like that... although the schema is unlikely to reside at
the namespace URI. However, an emerging technology called RDDL means
that it should be possible to find DTDs, Schemas, and other useful
stuff about SVG by going to the SVG namespace URL. Updating the
current namespace placeholder to be RDDL is on my 'to-do' list.
