out a whole load of redundant cruft that helps fleshlings follow the plot,
but has to be located and discarded by a computer.

Only if the compression algorithm knows enough about XML to know which
bits can be ignored. Which is what I'm proposing, basically.

Dude, we covered this point... read the thread!
