Actually, chapter 12.6 of the DSSSL spec. defines the flow objects and
says almost nothing about SGML at all.

Only very, very occasionally.

There is a DSSSL feature for getting the page number of an element. This
is used for cross references, tables of contents and indexes (among
other things).

"(page-number-sosofo) 

Returns an indirect-sosofo whose content is a sequence of character flow
objects representing the 
page number of the page on which the first area resulting from the
indirect flow object specified 
by the indirect-sosofo occurs."

This paragraph certainly uses a lot of new terminology, but none of it
is SGML terminology. All of it is DSSSL terminology, described in the
DSSSL spec.
