The following probably has bugs, and it was written a long time ago. I'd
probably do a lot of things differently today, but I don't see any point
updating this when there is atleast one working implementation out
there.

Microsoft have something similar in IE5, but that is MSXSL rather than
true XSLT. Their one is a lot slicker than mine. There are things you
cannot do in XSLT, but you can in MSXSL, in particular you cannot "see"
the XML declaration with XSLT. Microsoft may have updated that
transformation to proper XSLT for MSXML3, others on the list would know
more about that than me.

Comments are
now surrounded by PRE tags - preserves whitespace, but puts in a lot of
blank lines above
and below the comment

When script done, remove all whitespace (including carriage returns)
between the attributes 
part of the * template and the closing > of the opening tag a few lines
below (just after 
xsl:choose). Code will be one long line & harder to read, but it will no
longer put a space 
between the last attribute value and the right angle bracket.

Does weird stuff when DOCTYPE is present. Try it with a WML doc, seems
to go and get 
the external DTD and then displays the comments.
