> ParserContext.parseElement currently expects you to know what kind of metadata you expect to get out of an element and, depending on the type, may or may not require the element to be in the blueprint namespace.  Sometimes he requiest is mapped to a namespace handler,  and sometimes it's assumed that you are giving it a blueprint element (but it isn't checked).
> It would be much more convenient for writing sophisticated NamespaceHandlers if parseElement would work with Metadata.class as the type: this allows the parser to check namespaces, map to the correct namespace handler if necessary, and figure out what kind of metadata is needed for blueprint elements.
