$Web_Del_Sel deletes a global select element, preventing its further use and freeing any CCATEMP pages used by it. An overview of the $Web_Sel* functions is provided in $Web_Selp.
$Web_Del_Sel is a callable $function, and it can be run from a non-Janus Web Server thread.

Usage notes
- $Web_Del_Sel will delete a global select element, preventing its further use; an example of this is shown in $Web_Selp. Other than this, $Web_Del_Sel is not needed to perform any processing supplied by the $WEB_SELx functions; unused global select elements will simply have their contents migrate out of the buffer pool and remain as unused CCATEMP pages.
