One way is to just declare the record type in its own package:

  package RP is

    type RT is 
      record
        X, Y : Integer;
      end record;

  end RP;


  with RP;
  generic
    ...
  package GP is ...;


If the record type is itself part of a generic package, then you can
import an instantiation:

  generic
    ...
  package GRP is

    type RT is record ...;

  end GRP;


  with GRP;
  generic
    with package RP is new GRP (...);
    ...
  package GP is ...;



See also the Strategy example in the ACM patterns archive.  A storage
management package imports a storage node (record) type using the
technique described above.
