SHP file attribute query . . .

There are 2 ways:

  - use WMS/WFS to get service metadata or
  - do a simple query (any query will do) and use the [items] tag in a template to get a comma delimited list of item names

Fastest query would be an index query. It is a bit of a hack but it works and the same template can be used for any layer.
I added a section to the DNR Test Suite to show how:

All,

Any ideas on how to query a SHP file for all of it's Attribute columns 
through MapServer?

I'm wanting to set up a way to select which label to use so that the 
user can pick which label from the attributes available.  Do I need to 
build a middle ware for this?

It seems like a lot of work to keep a MAPfile up to date with regard to 
what the SHP has for attributes and a LABEL definition in the MAPfile.

Once I have a list of valid Column names I can pass the NAME in as a CGI 
parameter, but how to get the list through MapServer?

Any ideas?
