Notes on the Saxon implementation

Saxon implements the zero-argument function by passing a null URI to the registered `CollectionURIResolver`. The default `CollectionURIResolver` implementation supplied with the product handles this by returning an empty sequence, but a user-supplied `CollectionURIResolver` is free to handle this case any way it wishes.

If a user-defined `CollectionURIResolver` has been registered, the action of this function is entirely user-defined. A resolver may be registered using the `setCollectionResolver()` method on the `Configuration` object, or (in XSLT) using `setAttribute()` on the `TransformerFactory`. The `CollectionURIResolver` may also be nominated using the -cr option on the command line.

For details of the behavior of the standard `CollectionURIResolver`, see Collections.
