[jdom-interest] Namespace issues, et al.

1) The targetNamespace in the <xsd:schema> defines the
namespace for the elements defined.  Thus, <request> is in the
http://www.temporal-wave.com/spec/ namespace.

2) The definition for <request> specifies a local attribute
named 'session'.

3) You example doc uses a default namespace of http://www.temporal-wave.com/spec/
so the unadorned <request> tag is in the correct namespace, and the
unprefexed @session attribute is correct.  

So, yes, you have a document that matches your schema.

This doesn't affect the namespacing of the attributes.  The @session attribute
can't be willy-nilly glued to any other element.  It's defined as a local
attribute on the <request> element.  It has no namespace.

When you say you can't build this in JDOM, what exactly happens?  Should
be perfectly easy to read/build/write documents like this.
