RE: behavior

Weird, but correct. This language is full of surprises. If xsl:variable
(without select) has children, the value is a result tree fragment,
regardless of the fact that the children produce no output; and in this case
the equivalent node set to the result tree fragment is a root node with no
children of its own; the test xsl:if test=$x tests whether the equivalent
node set contains any nodes, which it does, because it contains a root node
with no children.
