I have no reason to believe I wasn't using the
the GNU version file (version 4.12) as the machine was running Debian.

I also tried using another machine with the FreeBSD version which was
definately different.

Thanks.  Ideally I'd like to see all versions of file improved.  I am
doing this largely on behalf of OpenClipart.org because I wasn't satisfied
with the initial assumption that this was too difficult to implement given
the inconsistency of most XML and I had to at least try and make it work
before giving up on the idea.  There are so many of the file formats I
used are XML based it is time for me to something about making file aware
of the more established standards at least (and maybe also work out the
magic needed for two of my favourites Gnumeric and Abiword).

Now that you mention it I suppose I should have escaped a space <svg\ but
then it is possible although rare to see <svg> more often there would be a
space and some other information but I dont understand the magic syntax
very well.  I thought I was doing pretty well to even get this to
correctly identify my slightly contrived SVG but I was a long way from
getting it to identify any of my real life SVG files.
