+<Log>Redundent Expression Elimination branch checkin. This branch is for major
+ optimization work being done. I expect it to be folded in on the main branch
+ within a couple of weeks.
+
+ Goal of branch: around 50% overall performance gain.
+
+ Major architectural changes
+ 1) Rip out cacheing in all iterators, and move the caching into XNodeSet
+(actually NodeSequence where the caching is done derives from XObject and
+XNodeSet derives from NodeSequence). Lots of other changes went into this,
+including rewriting of some of the xsl:key stuff.
+
+ 2) Implementation of a Visitor mechanism for the stylesheet and xpath
+components. Each component for an XPath event is passed an ExpressionOwner,
+which just has a getExpression and setExpression method, which allows us to
+create a list of these, and then be able to do rewrites. This should be a
+generally useful mechanism for all sorts of stuff, and should be considered a
+public API.
+
+ 3) Implementation of deepEquality methods for all XPath components, which
+allows us to see if two components are equal.
+
+ 4) Implementation of RedundentExprEliminator, which is a derivative from the
+new XSLTVisitor class, which runs over the stylesheet collecting xpaths within
+the same scope, and absolute xpaths that are not context dependent. These are
+then each reduced by walking the list and checking for deep equality (though
+global paths are always reduced). Reduction takes place by creating variables
+that have a special namespace and a non-legal local name. Both full and
+partial path reduction done.
+
+ Not done yet: Add back in the xsl:key caching that I ripped out (not a big
+deal). Could be skipped, with some risk.
+
+ Not done yet: Implement isLast function. With the new stuff, the last()
+function will be slower, so, since most cases are just checking to see if an
+item is the last, I want to rewrite foo[last()] patterns to
+foo[xalan:isLast()]. Could be skipped, with some risk.
+
+ Davanum performance test result: 4x increase in performance.
+
+ Datapower performance suite results: very slight decrease in overall
+performance. :-(
+
+ Smoke test results: All clear when run with Xerces 1.
+
+ To Do on this branch:
+
+ Christina trace/debug API enhancements.
+ Possible unroll of recursive evaluation.
+ Implement serializers directly off of ResultTreeHandler (and provide
+ContentHandler adapters).
+ Specialize and optimize serializers for 80% cases.</Log>
