I should have said "go back to following the Dexter model."

It's a frequently-cited model for describing hypertext -- pretty much
conventional by now. It defines the terms link, anchor, node, ...

In fact, I went through the excercise of surfing for a reference
just last night. It's in the June 2 (interim, unpublished) draft.
Dunno why I didn't send it to you.

I couldn't find that article online. But for some related articles,
try this query from the Harvest/Verity C.S. tech reports broker:

The Dexter model is the most complete and general formal model of
hypertext systems. Although, the composite concept that it formalizes
can not allow all kinds of inclusions. In this paper we show a
modification of the Dexter model that, through the anchor concept, can
model the handling of generic inclusions easily and validly. We also
show how our modifications form an extension of the Dexter model,
which can still be obtained as a restriction of the modified model.
