RE: [ubl] Namespace versioning
Title: Re: [ubl] Namespace versioning

Tony,

 

I am not talking about doing away with 
minor versions for the schema, only minor versioning of the namespaces.  A 
namespace is nothing more than the first part of a qualified name for elements 
and attributes - or if you like an artificial container of names that are unique 
within that container.  It is not, and in my opinion should not, be a 
substitution for schema location.  Our namespace string and schema location 
string are the same out of convenience and standardization - not because they 
imply the same thing.

versioning

Mark, what mechanism would you use for identifying the minor 
version of 
the Schema that an instance is valid for?  
Non-identification of minor 
versions is fine for systems that are 
always and instantaneously updated 
to handle the latest minor version 
of the Schema, but all other systems 
need to be able to identify when 
they have been sent an instance which 
corresponds to a new minor 
version that the system doesn't yet handle.

Cheers, Tony.
