House of Lords (Members’ Taxation Status) Bill [HL]

I am puzzled. Are my noble friends Lord Trefgarne and Lord Selsdon saying that Rockall somehow should be treated not as part of the British Isles, but that it could have its own citizens as part of a wider definition of British citizenship and that those people could sit in the House of Lords? I thought that it was very difficult to live on Rockall.
