Hi all, I am considering extending CPL to include context and presence switches. Now if I modify the cpl dtd file, I will obviously have to modify the cpl-c module of SER to understand it. Can anyone give me guidelines as to what files in the cpl-c module directory I should concentrate on?...cpl.c?? Many Thanks, Aisling. -------------------Legal Disclaimer--------------------------------------- The above electronic mail transmission is confidential and intended only for the person to whom it is addressed.
