  Just replace the hard-coded XML element with doc(...):

    ...
    for $a in distinct-values(
        doc('...')//author[@type = ('co-author', 'Faculty')]
      )
    ...

  Not tested.

  If your input is quite well structured, you can maybe
avoid the use of the // operator, which can be very not
effective.
