Does anybody know what is going to be the support of namespaces in ExtJS 3.0?

It is ridiculous to develop an internet based business application without support of SOAP services. So fullfeatured XML opearation API is a must. JSON is a kindergarden technology for transporting business data. If ExtJs aims to follow RIA requirements it must deal with XMLs.
Till the moment this becomes a fact, as SMAIL points, the client-side conversion is the only way.
