This is where I find it easier to keep the specialized parts of the
interface separate from the other aspects (like IContainer), but
that's a style issue as much as anything.

It's worth knowing that you can specify multiple interfaces here,
seperated by spaces.  You can also combine interface="..." with
attributes="...".

set_schema can also take multiple, space-separated schema, and
set_attributes="..." can be included as well.
