Class with join (2)

Hi again,
  I sort of got what I wanted by renaming my big taxon list to sites.dbf.
Now the mapfile with:

LAYER
  NAME sites
  TYPE POINT
  STATUS DEFAULT
  DATA sites
  CLASS
    SYMBOL 4
    COLOR 255 0 0
    NAME "BIbi Sites"
    EXPRESSION ("[TAXON]" = "BIbi")
  END
END

Does indeed give a subset of the full group of sites, but it looks like
far fewer than I want. Since there are multiple taxon records per site, is
the expression only being applied on the first record to match the shape
file?
