Tiled datasets with OGR

[Daniel Morissette]

Um... not sure why the STYLEITEM AUTO would not work with a tiled OGR 
layer, but anyway, a workaround for this issue would be to convert your 
tiled TAB files to a Seamless TAB Dataset using MapInfo. Seamless Tables 
are similar to tiled dataset, but the tiling is handled in the MapInfo 
driver inside OGR so MapServer sees the seamless table as a single 
MapInfo file. Then you'd just point to the seamless table (.tab file) in 
the CONNECTION string and STYLEITEM AUTO should work.
