Yes. @field_name identifies a node-set containing all the attributes named
field_name. Obviously there will be either 0 or 1 node in the set, since
it's in a predicate (each element in the child::* set is being tested
individually). If testing an empty node-set for inequality to a non-empty
string, you're always going to get true.
