As discussed in today's conference, we must synchronize our use of XML schema and common types. I would propose that we come up with some simple names for the schemas and standardize the namespaces. Here is a list of namespaces and schema that are currently used in our documents. xsd http://www.w3.org/2000/10/XMLSchema wsp http://schemas.xmlsoap.org/ws/2002/12/policy wsa http://schemas.xmlsoap.org/ws/2003/02/addressing wsrp http://www.ibm.com/xmlns/stdwip/web-services/WSResourceProperties wsrl http://www.ibm.com/xmlns/stdwip/web-services/WSResourceLifetime wsnt http://www.ibm.com/xmlns/stdwip/web-services/WSBaseNotification wstop http://www.ibm.com/xmlns/stdwip/web-services/WSTopics cdl http://www.gridforum.org/2004/12/CDDLM/XML-CDL/1.0 cddlm-components http://www.gridforum.org/cddlm/components/2004/11/06 cddlm-types http://www.gridforum.org/cddlm/serviceAPI/types/2004/10/11 cddlm-api http://www.gridforum.org/cddlm/serviceAPI/2004/10/11 As Steve mentioned, we also need to add a document that lists our common faults.
