[Serusers] Modifying CPL-C module

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??
