This is very cool.  I have been trying to figure out a way to take Joshua
Allen's OPML and XSLT work and make it work in this manner.  This is a
perfect way to do it.  I modified the ioLinks macro to output a "View It"
option.  Have a look at my weblog for an example:

http://radio.weblogs.com/0001134/

I have tested this a few times now.  The first node is not selectable or
expandable.  This could be because the XSLT declaration is coming before the
XML declaration.  I'm not sure, just a guess.

Thanks for making this available.

This is very cool.

I wanted to take a look at some of these Instant Outlines without
leaving my web browser, so I wrote a Java servlet that opens them as
XML files using an XSLT transformation. The details are here:
