Please review a small localized point fix for an error when updating
relative links in doc comments.
The problem is that `name` or `id` attributes may be updated (and should
not be) when updating links for use in a different context.
There are other more systemic design problems in the surrounding code
that will eventually warrant attention, but this is for a specific
fixable error.
