[Serialization] IBM-SE-007: Definition of round-tripping

Serialization Section 4, "XML Output Method": The paragraph before the 
bullet list says that the round-tripped data model must be "the same as 
the starting data model". This should be clarified to mean the data model 
after the "normalization" (or "documentization") process described in 
Section 2.
