You've mentioned problems with data consumers but you haven't provided an example. I am not interested in regressing to a less detailed tagging scheme for legacy software support, much less the huge mechanical edits necessary to follow through with it. Perhaps software can be updated to reflect actual usage of these elements and tags.
