Code

function userreference_autocomplete_process($element, $edit, $form_state, $form) {

  // The userreference autocomplete widget doesn't need to create its own
  // element, it can wrap around the text_textfield element and add an autocomplete
  // path and some extra processing to it.
  // Add a validation step where the value can be unwrapped.

    // to be passed down to the nested element.
