Some small changes would make this a _much_ more useful step:

 1) Add an 'attribute' option, default value 'xml:id';
 2) Generate sequential integers, and default the 'prefix' option to
    '_';
 3) Remove the 'must detect duplicates' error.

That way, I can use this to generate XSDL-style keys, or keys for
stylesheets, etc., and people who don't want to be constrained to
NCNames don't have to be.

Removing the error is much less of a big deal than it might at first
appear -- in its current form it doesn't guarantee no duplicates, and
people using this to fill gaps in a set of partially-labelled
documents will expect to use a prefix and/or suffix to avoid
collisions.

I request discussion on this to be limited to 5 minutes, followed by
an up/down vote.
