That's exactly the struggle I had when implementing werken.xpath,
way back when.  Using a literal reading of the spec, I opted for
java.util.Set for my NodeSet, and that failed me when it came to
proximity predicates.

Figured that preserving order, while not explicitly stated, was
at least an implementation requirement.
