This seems compelling. I agree, then. @onlyreplace on <base> defines
the id-list, and then @onlyreplace on links/forms says "I should carry
the onlyreplace semantics". In the former case it's a space-separated
list of IDREFs, in the latter it's a binary attribute.

Hmm? No it doesn't. The @onlyreplace still makes the page *way*
easier to handle. Needing a little bit more js to hook extra behavior
around doesn't seem unreasonable. (It's better than refreshing the
navlist just to highlight a new section.)
