One of the main requirement for tiled layers is that all files need to 
share the exact same set of attributes.

Note that if you are a MapInfo user you can create a "Seamless Table" 
with all your files directly in MapInfo and then point MapServer to the 
seamless .TAB file in your OGR CONNECTION and MapServer will take care 
of the rest. This is exactly the same concept as MapServer Tile Index 
files, but in the MapInfo world, and MapServer supports both.
