| Andrew,
| What about images? or block level elements, which can't be contained
| in inline elements?

Again, we are speaking here about pure HTML. Imagine that there no CSS at all in 
the Universe.

>From HTML point of view images are special type of characters (or single 
character words)
- they positioned inline as other text (floating images is an exception) .
There are only two types of "blocks" from HTML point of view - document itself 
and table cell.
All other tags (not elements, sic!) has no visiual indication that they are 
blocks (no borders/backgrounds) -
thus some hypethetical renderer can forget about DIVs, BLOCKQUOTEs, etc 
immediately after parsing.

Parsing/layouting here is a simple incremental process - build list of tagged 
(by hyperlinks) words and their postions by
using markup rules. To render just walk through all of words and draw them at 
their positions.
Plain HTML renderer is significantly simpler than HTML/CSS renderer - it does 
not require DOM -
just list of words. Or it is "flat DOM" if you wish.

I guess that this simplicity was deliberate intention of HTML inventors.
