* could be a subclass of the scheme. Another way is one instance of
* a URLScheme class instance for each URLScheme we support, and one URL
* class for each manner of treating the scheme : a Hierarchical URL, a
* non-hierarchical URL etc.
\par
* Deferring the decision, its a type code for now. RBC 20060507.
