Draft Proposed Answer to Bjoern Hoehrmann [amended]

[Amended to point to published WD of SpecGL]

Thank you for your detailed comments and contribution [1] about the 
complexities of properly handling normative references.  The QA Working 
Group entered this as issue #984 [2], and has accepted the comment.  We 
have changed the text of SpecGL [3] to encompass the breadth of the 
complexities you described, while at the same time have tried to preserve 
reasonable brevity in the SpecGL text itself.
