What does the term "topic map graph" mean?

The best definition I have been able to find is "the set of
interconnected topic nodes, etc., that result from processing a topic
map document."

(1) The term "node" is a little overloaded right now.

One thinks of DOM nodes, even nodes in dynamic HTML, and therefore one
thinks, wrongly, that standard XML tools are sufficient to process
topic maps. (They are necessary, but not sufficient.)

Part of my confusion is that I am used to believing that the topic map
graph is isomorphic with the <topicMap> markup. But this is not so,
given that the creation of topic nodes in the topic graph can be
"demanded by" the presence of elements in the <topicMap? document that
are not <topic>s.

Perhaps, in the context of TM documentation, "pnode" (for "processed
node")?

(2) Are all the pnodes in a topic map graph of type "topic"?

(3) Are the interconnections between pnodes typed?

Lots of other questions but these will do for now.
