is mathplayer installed on your IE5.5 client machine?

Looking at the <ie5:if bits of pmathml.xsl (it's been a while) I see
that in the ie5 variant I don't try to do the arcane tests to find a
suitable mathml renderer, and just do one javscript query on the
registry to see if mathplayer is installed, if so it adds a mathplayer
object and pi to the head, if not it doesn't, but just processes the rest
of the document (so you'll end up with unhandled mathml elements in the
body). This behaviour isn't over documented, in fact the table in
http://www.w3.org/Math/XSL/Overview-tech.html
appears to claim that the wd-xsl code will work in more cases.
Sorry about that.

Given the fact that Microsoft's wd-xsl language isn't really supported
by anyone these days I'm tempted to fix the documentation to say it
doesn't work with multiple rendering possibilities rather than extending
the code. However if it doesn't work even if mathplayer is installed,
that is a bug that I should try to fix...
