Markup is not the only way to determine the structure.   It is the only one
supported widely by AT today -- but this guideline only says that it must be
separable.  If it can be separable based on the visual presentation -- then
it is separable and that would satisfy.    In HTML - markup is the way to do
it - and the way that the std specifies.

This is important since some people will need to be able to
get all of the
information and structure out of the content so that it can
be presented in
other forms.

Ok, this is clear. But problem is:
1. structure is the *logical or conceptual structure of
content* or *the formal representation
of structure in markup*, or  both, or other?
2. define markup language. structure in html means different
things than in xml (semantic vs maybe for nothing semantic).
3. for me, node is presentation: logical structure require
presentation (rendering), hierachical structure not. A book
organized in chapters ecc ecc, is logical structure of book,
a system for describing the logical structure of text.
A hierarchical structure is  an organization of things
(members) using an asymmetrical relationship. Every member
must be reachable from any other by following the
relationship. There must be no way of coming back to a
member by always following the relationship in the same
direction.
Sorry for my orrible english :-)
