I said what I said after reading the latest STX spec and only in the 
context of this discussion (which is "taming SAX"). I have to agree with 
Uche in saying that STXPath is very nice-- but may not be exactly what 
we are shooting for. Surely predicates are viable in many cases in 
partial scans such as:

   <bar test="foo">


But when considering /foo/bar[baz3="test"]/baz1


This predicate's value cannot be ascertained at the point of the baz1 
startElement event in a single event look ahead model. At least that is 
what I heard through the grapevine.
