Well at the very least can we allow all characters between 0x20 and 0x7e
except for: "&/<>\
Why hasn't the patch from kern/104389 made it in to geom? It's been almost
20 months since any activity on it. The last patch seems pretty good,
except for NUL and SOH (0x00 and 0x01), but can't you just use "&#xx;"
encoding for those also? XML has its own limitations. I don't think it's
worth limiting everybody else just because of this XML bug.
