Its one possibility. You can also build programmatically the definition tree,
and save it / read it as a serialized object.

I don't know about a standard way to revers digester code. Could be
interesting.

Tile use the digester to read xml files. You can reuse it to read any file
with appropriate format. But if you want to read from a read DB, you can only
reuse part of it.
This could be an interesting extension/new feature for Tiles.
