I've got many pages like
https://id.loc.gov/authorities/names/n2001028682.html  (stored in WARC
files)

I've got names.madsrdf.xml.gz which is all the names in madsrdf, but it's
disaggregated rather than in the format exampled in
https://www.loc.gov/standards/mads/rdf/ so it's not really amenable to
processing in XSL. I'd prefer not to spin up a triple store and reasoner of
any kind.

I suspect that what I need is the MARCXML, which I'm familiar with
manipulating with XSL and has all the subfields I need explicitly marked.

As I work, I've been documenting the differences I find between LoC and
wikidata, on the understanding that bridging LCCNs and wikidata is unlikely
to be the work of a single person, see
https://www.wikidata.org/wiki/User:Stuartyeates/Wikidata_-_LoC_ontological_mismatches
