one can sort this out by answering a fundamental question: are names
constants or variables? despite the variation among and discrepancies
between the respective models, the standards describe operations which
align, in that they treat names as constants. given that, the models can
be unified to describe names as constants and variations can be handled
when parsing and/or serializing.

it may well be that a significant effort is necessary to fix this in the
java world. judicious class specialization could reduce it. better late
than never.
