[Nml-wg] Schema changes

[Chin Guok]

IMHO, I don't have a problem with meeting the requirements of the charter 
and standardizing a single layer schema.  As John pointed out, the NSI is 
highly dependent on the NML to develop a schema that will work for us.  As 
it stands right now, the adaptation functions will be an extension to the 
single layer schema which I'm perfectly fine with.  It would be a big 
concern if adding the adaptation will cause a complete rework of the 
schema, which would result in the depreciation of the single layer schema, 
and void the implementation by some early adopters of the schema (i.e. IDC).
