SOA RA Section 2 Updates

[Danny Thornton <danny_thornton2@yahoo.com>]

Section 2 is almost up to date with the models in Section 3, 4, & 5.  The Semantics in a SOA Ecosystem model was a late addition.  That should be added to Figure 2 with a pointer to the Interfaction CSF.

Line 498 & 499 should be updated to read, "Interaction encompasses not only the mechanics and semantics of communication but also the means for discoverng and offereing communication."

Any deletion of models will require updates to Figure 2 and associated text.
