The expression xx means ./child::xx, it does not mean the QName ("", "xx");
and the same remains true if you write it as Q{}xx. Bare names in XPath
expressions are short-hand for a selection on the child axis.

It's a shame that we didn't add a QName constructor function taking an EQName
as input, something like QName("{}xx"); but that wouldn't be very much of a
convenience over QName("", "xx") unless you are reading the EQName from
somewhere else.
