Because it contains a ton of redundancy

Exactly? What's your point? Things have to be low entropy/contain a lot of redundancy in order to compress well.

If it were a more compact format, it is likely both the uncompressed AND compressed sizes would be smaller.

By your logic, if you 10x'd the length of the XML tags in XMPP then it would be even better since you you would get an even further improved compression ratio.

To be clear, I don't have a problem with XML in XMPP since it is negligible overhead, but "it compresses well because it is full of redundancy" is not the argument that should be used to justify it.
