Quite, um, 'true'. :) I usually assume people are familiar with the data
types, but I'm probably being naive when I do so.
test="$foo" is like test="boolean($foo)". Following the rules for
XPath boolean(), and the XSLT spec's info on result tree fragments, the
test will be true if $foo...
is a boolean true [this isn't actually stated anywhere, is it?]
is a string with a non-zero length
is a non-zero, non-NaN number
is a node-set with at least one node
is a result tree fragment
Result tree fragments are true because they always contain a 'root' node.
