Sorry, Karen, I routinely clicked on "reply" without realizing it would only go to you. I'll get it right this time.
I also wanted to touch on the fact that LCSH wasn't designed as a faceted scheme, so what we're really trying to do here is see how well subfield $a in MARC heading and reference fields serendipitously maps to what might be considered a "principal facet" in a faceted scheme. In my example below, the War of 1812 is represented in subfield $a of a UF reference, which could then be used as an anchor to identify this record (and the longer three-term heading) as representing a "candidate facet". (The battles of the War of 1812 are each represented in subfield $a of the heading field and so would qualify as "principal facets" in this thought experiment, so it's rather perverse if the selection criteria exclude the war of which they were a part.)
I think including the UF references (when they consist of a single $a subfield) would capture many, if not most, of these situations.

Ed, are you suggesting that single-facet cross references be used?
That is an interesting idea. Presumably they would have the same
identifier, but wouldn't be the prefLabel. (But you didn't send this
to the list, it looks like -- can you do that?)
