The rules for comparing a node-set to a boolean have changed. In XPath
an expression such as $nodeset=true() was evaluated by converting the
node-set to a boolean and comparing the result: so this expression would
return true
if $nodeset was non-empty. In XPath 2.0, this expression is handled in
the same way as other comparisons between a sequence and a singleton: it
is true if
$nodeset contains at least one node whose typed value is true.

This bothers me. What if the node set contains multiple nodes, some of which are true, some of which are false, and some of which are indeterminate?
