> The not() function works well with properties, but not quite with relationships. An example of what doesn't work:
> /s-ramp/wsdl/Part[not(element)]
> That should return all Parts that do *not* have an element relationship. Since relationships are found by doing a JOIN, it's actually tricky to invert. Right now I think the query engine will produce something that would return all Parts that have some *other* relationship - but it won't return Parts without any relationships at all. I'm not sure how to do the latter other than by using an IN with a subquery (which is supported by ModeShape but is non-standard).
