I could create a single new keyword (e.g. TILES) and use the older
keywords to
populate members of the new object. That's how styles work so that
older map
files don't break. In effect:


would be the same as

  DATA 'foo'

To take advantage of filtering you'd have to move to the TILES object.
The only 
side effect would be that mapscript would break since
$layer->{tileindex} isn't
real anymore. That was the same case with styles.

This seems a reasonable compromise to me anyway.

I am concerned by the fact that the new tileindex object would break 
existing mapfiles.  Could we stick to shapefile tileindexes for this 
release for now, since we don't have much time anyway, and perhaps in a

later release we could move a tileindex object and support tile indexes

in any format?

I suppose the main drawback of this approach would be that we would
to create TILEFILTER/TILEFILTERITEM which would have to be deprecated 
later when we create the tileindex object.

I dunno.... I think we should try to avoid breaking older mapfiles 
unless we really have to... that's always a pain for users to upgrade 
when we break the mapfile format.
