Soap Serialization and Deserialization Rules for C++ Object

Hi, 
This is my First time i'm writing in a mailing list and i apologize first for my english and second if i'll make wrong questions.

I recently started to study  the SOAP 1.2 recommendations (Part 0, Part 1 and Part 2). I'd need to know something about "Soap Serialization and Deserialization Rules for C++ Object", but in the recommendations i can't find anything that help me. 
Probably because i do not look good. 
Could you direct me to the right specifications that may be useful for my intent? 

Thanks

Best Regard
