Subject: Re: [ubl-ndrsc] Rule: 107 XSD prefix
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".
