More or less. It is the parse tree of the document with some other extra

you can have different sets of transformation rules, grouped into a

(element section
	 (make sequence
	       (with-mode extract-title-text
                   (process-matching-children "TITLE"))

you process the subtree twice.

Firstly you just process the children that match  "TITLE"
using the rules in the mode extract-title-text

and then you process all the children and so get the title again
if there is any rule in the default set that would match the title
