[Serialization] IBM-SE-013: XML v1.1 vs. Namespaces v1.1

Serialization Section 4.1, "XML Output Method: the version Parameter": 
This section should explain what it means to serialize a data model using 
XML Version 1.0 or Version 1.1. These versions are distinguished mainly by 
the characters they allow in names. Does the data model need to specify 
which XML version it is using? (Currently the data model does not provide 
any way to do this.) What happens if serialization is using XML Version 
1.0 but it encounters a name that contains a character in the Version 1.1 
character set?

Also, this section should specify whether XML Version 1.1 interpreted to 
include Namespaces Version 1.1 as well. If not, should a separate version 
parameter be defined for this purpose?
