Wouldn't be much point mapping it to Esc, it's a modifier key.  Mapping 
alt and meta to the same key is the default for PC keyboards under X.

A compose key is used for producing accented characters and is a prefix 
key, not a modifier.

Compose followed by ` followed by e gets è

Compose, l, - gets £
Compose, c, o gets ©

And so on.

The meta key ors a key's character code with 0200, apparently, to give 
you an unsual bunch of characters on some keys.  Emacs uses those 
characters for extra meta functions but if nothing else makes much use of 
them then I'm happy to dump it.
