[Serialization] IBM-SE-006: Schema used in round-tripping

Serialization Section 4, "XML Output Method": The paragraph before the 
bullet list says that "if a new tree were constructed by parsing the 
[serialized] XML document and converting it into a data model as described 
in [Data Model], then the new data model would be the same as the starting 
data model." But this conversion process involves validation, which is 
schema-dependent. We need to specify that the schema used in this 
round-trip process is an effective schema consisting of the in-scope 
schema definitions in the static context.
