To which idea is this +1 directed :-)
I am getting a bit nervous watching PropertyName being used as a placeholder
for a generic "qualified" XPath. Still I guess I understand why it is taking
that shape.
So is your +1 for the idea of:
Query.getAttributes(): List<PropertyName> // property name may refer to a
complete xpath
With this in mind getPropertyNames and setPropertyNames would then become a
shortcut methods for the above List.
