Yes (and I changed that on my system), but this will impact just the
precise details of the web-browse tool's metadata display; the images
themselves (the SVG files) will not be impacted by this at all
(including in the browse), so I consider this less urgent, i.e., not
urgent enough to warrant my panicking and scrambling to get it a patch
in and turned around in time for this release, which is what I was
about to try to do if svg_validate did stuff with the metadata.

Cool.  One less thing to need to fix :-)
