Excellent! I had previously been using things like 'not elem c+n+o+h+s' in
my scripts. Using 'metal' will match my intent much better. 'Sidechain'
will be appreciated as well.
I would suggest 'ligand' and 'ptm' selectors to distinguish nonbonded and
covalently bonded hetatms. Although I'm not sure how non-standard amino
acids would fit in to those terms.
