I have only one layer (plans) and it is a polygon shapefile. It has
four attributes, title, origin, themekey, and url. I need the layer
to be queryable through getCapabilities and for the response to be
formatted as an HTML document as a <table> construct, one row per
returned feature. I'd hope that since one of the attributes is a URL
that this would be exposed as a hyperlink rather than as text. The 
interaction will be to click on the map and have all polygons that
are 'skewered' returned as a result.

I gather I must add WMS_FEATURE_INFO_MIME_TYPE "text/html" to the WEB
object. But what, beyond TEMPLATE 'dummy' do I put inside the LAYER
description?
