Thanks to all who responded about why boolean43 should return true.
You guys really know your XSLT.
I'll put in a bug against XSLTC, since it returns false.

Hi Tom. An RTF has an implicit root node, so it is never empty. See
http://www.w3.org/TR/xslt#section-Result-Tree-Fragments (which the comment
in the test should reference). It states: "A result tree fragment is
treated equivalently to a node-set that contains just a single root node.

This question was a hot topic for debate a while back, so I'm not surprised
that you're perplexed by it. Here's the relevant section from the
recommendation:

I think the point is that the variable created contains just a single root
node with no children and
since a " node-set is true if and only if it is non-empty" TRUE is
returned. See sections 11.2 XSLT
second bullet, and Xpath 4.3 (Boolean) second bullet as well.

Tom --
Don't feel bad. This is very confusing. Even Mike Kay's book had it
wrong in the first edition. I corrected this in XalanJ way back when.
In XSLT 11.1
(http://www.w3.org/TR/xslt.html#section-Result-Tree-Fragments), it
states: "A result tree fragment is treated equivalently to a node-s
