Is the section "Making changes to the Codebook Framework" a subsection of the section or a section parallel to "Multiple-relationship Business Obects?" If I use eBizObj, do I need to follow either of these sections?

I found this site and see references to MM version 2.06 and 7. Are
these updates only for the people who have purchased the framework? I have the MM document version 2.0 from Compuserve and your Oak Leafe web site.
