Compressing XML at a higher layer, where the compression mechanism "knows"
the grammer being used, can be considerably more efficient than compressing
at a lower layer. That appears to be the conclusion found in the paper
referenced previously: http://members.dencity.com/duckgirl/uni/report.htm 

OTOH, I've been looking at compression in SSL for an unrelated project
(compressed SSL tunnels for NNTP). This works quite well where you are using
SSL anyway. At the moment the only common compression for SSL is GZIP/ZLIB.
