OQL is not supported and we don't plan do it in the future. (right people?) If
you need a query language, then you may express your stuff in XML (or wait for
DOM wrapper that is planed for the future) and use XPath or any other XML query
lang. If this isn't possible, then using any query lang is probably not a good
idea. Why do you think OQL is needed?

Never, I think. It will be removed because it doen't fit into the current ozone
architecture, IMO. (other opinions here people?)
