Intuitively, the above SGTM wrt programming languages.

If we could find HTML equivalents of the above notions, that would be
very good for consistent UX.  But if that turns out to be hard or
far-fetched or impossible, we could alternatively come up with
HTML-specific interpretation of these abstract notions.  As long as
the result makes sense to users who edit or view HTML files, it would
still be okay, I think, even if the relation to programming language
construct is more remote.
