<div style="direction:ltr; font-family:Tahoma; color:#000000; font-size:10pt">Hi all: Been working on an RFC to help mainly with performance issues related to WFS queries (via OGC Filters) and MapServer attribute queries. It involves marshaling MapServer logical

 expressions into a format native to the underlying driver (most likely a SQL snippet). MapServer expressions exist as a sequence of tokens (literals, operators, attribute bindings) and is should be possible to construct native expressions from these.</div>
