Chapter 8 (Collections) of the DRM describes <mutable-collection> and
<stretchy-collection> as:

  "Instances of <mutable-collection> can have their elements changed
  after they are created. Instances of <stretchy- collection> can have
  keys added and removed after they are created."

Chapter 12 (The Built-In Functions) of the DRM describes
type-for-copy.
