Actually, the main reason is that SSAX is a horrible mess which has
many completely unrelated procedures all mixed together.
There are several egg that provide different sets of procedures
from the SSAX project.  Most eggs include all files from the SSAX
project to make it easy to update them, but they don't install them
all.

The proper place to do this is in the sxml-serializer egg, and
we definitely should *not* be adding random procedures to sxpath.

(the *REALLY* proper way would be to drop SSAX and create a sane
and consistent XML library from scratch, maybe reusing some algorithms
from SSAX, but that's a whole other story...)

Cheers,
Peter
