Hello Hixie!
Again, thanks for replying to one of my very old emails. Also, note the
email address change.

Thanks for the idea.
I don't think a document outline DOM API is something that has a great
deal of demand. It's also something that could be implemented in a
JavaScript library or on the serverside. Generally speaking we want to
keep the APIs in the spec to a minimum, limiting them to primitives that
are useful for a broad range of purposes, rather than having many
special-purpose APIs. So I haven't added the outline DOM idea to the
spec.
The main reason for having this section is to enable scripts and user
agents to create outlines in user interfaces without ambiguity about what
is a section. This is an area that has historically been very much
underdefined. We shall have to see, with implementation experience,
whether this is useful or not, and what UA implementors will do with it.
Cheers,
I'm skeptical about UAs implementing the outline algorithm.
If there would have been a very high demand for UAs to implement some kind
of document outlining algorithms, that would have happend already, with or
without any standard algorithm.
However, we have seen sites which create their own document outlines. Why?
Because the demand was even higher. I've created my own document outlines,
specific to my documents (either manually, or scripted).
Also, let's look at UserJS, Widgets and even UserCSS. I've seen UserJS
scripts which generate document outlines, same goes for CSS. Of course,
CSS is very limited compared to JS - but yes, I've seen such user styles.
Given Widgets are small web application packages (HTML+CSS+JS+etc), it is
conceivable some of them will also need document outlining.
I agree there's a demand for document outlining within an UA, but that's
all theoretical, in ones imagination. I did think long time ago, and I
still do, about how good would be to have UAs which implement document
outlining and several other features which would really make *semantics*
more obvious for the average Jane/Joe user. Yet, *today* the "need" is on
the web.
Cheers,
Mihai
