Reference to a JAXB type (from JAX-RPC.)

A reference is a Java type (represented as a TypeMirror) and a set of annotations (represented as a Element). Together they describe a root reference to a JAXB type binding.

Those two values can be supplied independently, or you can use other convenience constructors to supply two values at once.
