Pete,
actually this is documented in
https://mapserver.org/input/vector/ogr.html#tileindex-with-ogr and
tested in
https://github.com/MapServer/MapServer/blob/1a45e6074b71738e576563ac39f60fd96ded50eb/msautotest/wxs/wfs_ogr_tileindexmixedsrs.map
So for a OGR vector layer, the value of TILEINDEX must be a shapefile or
a OGR datasource name, not a MapServer layer, contrary to raster support
(contour layers use raster logic underneath).

I hope that this still works with Mapserver 8. It would be nice if
you could make a test and compare OGR vs POSTGIS connection types.
This test is the closest I could find of ”layer-as-a-tileindex of
vectors" that makes me think it should work:

What version of MapServer are you using?
Can you try this mapfile on your version of Mapserver?
