The whole point of XMLS is to work with infoset items rather than text. If you compress text with LZO (or any other text-based compression scheme) you still have to convert to and from the infoset as an added processing step. I've actually renamed the new code as XBIS, partially to emphasize this (and partially because xmls.org was already taken when I looked into getting an appropriate domain earlier this year...). - Dennis
