Stefano Mazzocchi of Apache Cocoon project fame (now left that project)
has developed a binary serialization of SAX that is significantly faster
to load than the original XML (than Xerces non-validating mode).

I think he did some further work on it to make the binary format
smaller...

(warning that page contains the compiler/decompiler itself as a Base64
attachment)

But then this is getting off-topic...
