Searching for cProjects.xsd?

Hello Experts,

i like to know the definition of a cprojects xml. So i am searching a little bit around with the help of google for the suitable xsd-schema and find the following SAP information:

My problem is that a bsp-application "CPROJECTS" doesn´t exist in our PPM 5.0 with SP10 😔! Can anybody help me or send me the "cProjects_xsd"?

Best regards,

Andreas
