It would be nice to have a list of possible values for a selected column, for
situations in which the user is unfamiliar with the data.

This could be done through the DISTINCT function of the WFS interface (although
I don't think Mapserver WFS supports this one at the moment ... ).

<ogc:Functions>
<ogc:Function_Names>
<ogc:Function_Name nArgs="1">MIN</ogc:Function_Name>
<ogc:Function_Name nArgs="1">MAX</ogc:Function_Name>
<ogc:Function_Name nArgs="1">COUNT</ogc:Function_Name>
<ogc:Function_Name nArgs="1">DISTINCT</ogc:Function_Name>
</ogc:Function_Names>
</ogc:Functions>
