That's my interpretation.

The "object" I imagine has three attributes: namespace URI,
localpart, and prefix. It would unpack to two values: URI &
localpart, and comparisons would only operate on those two as well.
The advantage is that we get the prefix for those who want it,
single object comparisons, and no extraneous parameters to the call.
I don't think *this* is available using the non-object approaches.
Whether the objects are extension types or classes is irrelevant to
