/**
* URI class to be used for cases when a simple URI actually resolves to some
* other sort of URI, with the latter being what's loaded when the load
* happens. All objects of this class should always be immutable, so that the
* inner URI and this URI don't get out of sync. The Clone() implementation
* will guarantee this for the clone, but it's up to the protocol handlers
* creating these URIs to ensure that in the first place. The innerURI passed
* to this URI will be set immutable if possible.
