Re: [ubl-ndrsc] Rule: 107 XSD prefix

[Chin Chee-Kai <cheekai@softml.net>]

Eve's right;  XML spec doesn't require a fixed prefix.
And specifying a fixed prefix to associate with a given
namespace value seems to go against the XML spec's spirit of 
having prefixes as mere "bins" to hold the namespace values.

On the other hand, some implementations do have (questionable)
"features" that for various reasons process fixed prefixes
(e.g. "xs" or "xsd") or are not that agile in managing
namespace dynamics.  This situation might improve in time.

But having heard Eve's point, I agree with Eve's version,
but prepended with:


[R 107]  If a fixed prefix is used, then the prefix should
be "xsd", and all W3C XML Schema constructs in UBL schema 
modules must use the "xsd" namespace prefix, bound to
"http://www.w3.org/2001/xmlSchema".
