I can also back this up anecdotally. Having gone to the effort of
implementing the WAP forum's WBXML format with a customised dictionary
of element names for my application, I doscovered that simple gzip
compression using libz gave far better results. If I primed the
compressor with a dictionary of expected element names, there was an
even more significant improvement.
