Those are just a pull variant of a SAX parser.

People at BEA have done some work on that (They call it token stream):

Daniela Florescu, Chris Hillery, Donald Kossmann, Paul Lucas, Fabio 
Riccardi, Till Westmann, Michael J. Carey, Arvind Sundararajan, Geetika 
Agrawal: The BEA/XQRL Streaming XQuery Processor. VLDB 2003: 997-1008

The XTiSP system which was presented at PLAN-X in January seems to have
something similar as well:
# XTiSP presented by Keisuke Nakano (UTokyo) http://xtisp.psdlab.org/ 

XML pull token streams also used extensively inside the Galax's query 
engine.

There are probably other projects using those.
