Yes. Random vs. sequential access is an othogonal issue.
Sequential Random
+----------------------------------------------------------

Push | SAX (recursive visitor)
|
Pull | Pull Parser DOM
|
+-------------------------------------------------------
The confusion arises since SAX and DOM are different
in two regards: (a) processing model (push vs pull)
and (b) access model (random vs sequential).
The XML Pull Parser is an example which is SAX-like
in that it is sequential access, but DOM-like in that
it has a pull interface. The other permutation
is a recurisive visitor interface. You can scan
the SML-DEV archives if you'd like more information
on this... it doesn't seem to be as useful as the
other three permutations.
Best,
Clark
