See my response to Rick, which I think answers your question.

Subject: Re: [Rails-devel] Rails-devel Digest, Vol 27, Issue 5

I'm keen to try and understand the relationships here as well, with
the recent 'tile 4' problem I saw that it was incorrect both in the
Tiles.xml, as well as the TileDictionary files.  Is there a script
that I've been unable to locate that builds the game specific
Tiles.xml given the TileSet.xml, or are the changes for each tile
propagated manually each time there is an update?
