Thanks Florent for useful pointers ... I do have some difference of
opinion to the below point. Kindly see my remarks below.

I think, as others explained, test="@married" is correctly written
(Andrew, infact said test="@married" and test="exists(@married)" would
result in same behaviour.

As written in spec, and you also wrote in this mail, "for non empty
sequence of nodes, EBV is true". test="@married" returns true if an
attribute 'married' exists. Please correct me, if I am wrong.
