It's important to note that an XML stream can be very highly compresses with
standard tools like WinZIP.  I have an XML file that's about 20K size, which
includes many repititions of a small number of tags.  WinZIP produced 97%
compression on this file!

The standard Java library includes a zip utility class for zipping/unzipping
streams, so it's possible to dramatically reduce transmission bandwidth
while retaining long, descriptive tag names.
