Subject: Re: [ebxml-msg] Re: [ebxml-cppa] Re: v. 2.0 ebXML xsd schema directory
Rich: I agree with your first point. With respect to your second point on referring to the canonical location http://www.w2.org/2001/xml.xsd, I like to bring your attention to the following excerpt from that schema: <xs:annotation> <xs:documentation>In keeping with the XML Schema WG's standard versioning policy, this schema document will persist at http://www.w3.org/2001/03/xml.xsd. At the date of issue it can also be found at http://www.w3.org/2001/xml.xsd. The schema document at that URI may however change in the future, in order to remain compatible with the latest version of XML Schema itself. In other words, if the XML Schema namespace changes, the version of this document at http://www.w3.org/2001/xml.xsd will change accordingly; the version at http://www.w3.org/2001/03/xml.xsd will not change. </xs:documentation> </xs:annotation> I think we should set the xsi:schemaLocation for the xml namespace to http://www.w3.org/2001/03/xml.xsd. -Arvola ----- Original Message ----- From: "Rich Salz" <rsalz@zolera.com> To: "Arvola Chan" <arvola@tibco.com> Cc: <ebxml-msg@lists.oasis-open.org>; <ebxml-cppa@lists.oasis-open.org> Sent: Friday, January 11, 2002 3:42 PM Subject: Re: [ebxml-msg] Re: [ebxml-cppa] Re: v. 2.0 ebXML xsd schema directory > {I'm not a member of the CPPA list, so they won't see this :} > > According to the XML namespace standard [1], > The prefix xml is by definition bound to the namespace name > http://www.w3.org/XML/1998/namespace. > So the declaration is not required, but it might not be illegal to have > it.
