Do I understand that correctly that you propose to put the exact names of the predefined structure types in the role attribute and map to those type for tagged PDF? role="H1" would lead to a /H1? I think that should cover most normal use cases. So +1 from me on that.
In some future luxury version, however, I'd imagine allowing to define a mapping in fo:declarations (or in the configuration) so people can really put the original tag names in the role attributes and then use that mapping to produce the right structure type in tagged PDF.
