This is the kind of reference scheme I asked for in my note on HTML
Diffs (a generalization of annotations). Looks like overkill, though;
is it worth numbering by type -- "fourth H1" as opposed to "fourth
object" -- since it is probably better to avoid applying diffs to
incorrect versions via the hash checks Nat mentioned?
"Objects" in SGML sources are easy to define, just divide the source
into tag instances and the text among them, and number sequentially.
Then we'll want a way of referencing tag substructure, say "the value
of the HREF parameter of the 10th object".
