So what we do is create a set of helper classes that will expose both the "known" core Notification system namespaces, as well as those that can be derived from the DOM Document (Document exposes these but through a different API than XPath NamespaceContext). We create CompoundNamespaceContext that consists of both of these constituent namespace contexts (so that our core NamespaceContext takes precedent...nobody should be redefining these!). We can *then* use fully qualified XPath expressions like: /nreq:notification/nreq:channel ...

The solution is to use a namespace naming convention coupled with the defined content type name in order to generate the canonical namespace uri for any custom content type. ns:notification/Content<Content Type name> e.g. ns:notification/ContentSimple, or ns:notification/ContentEvent We then construct an "ephemeral" namespace prefix to use in the NamespaceContext/XPath expressions to refer to this namespace URI. e.g. contentNS_<unique number> It doesn't (shouldn't!) matter what this ephemeral namespace is. We then define a temporary NamespaceContext that consists only of this ephemeral namespace mapping, and wrap the existing XPath NamespaceContext (the nice one we set up above to do our original qualifizzizing) with it.
