I'm not familiar with the Cambridge Communique.  The link returned a 404.
After a bit of searching, I was able to find references to it in the list
archives.   The refrences seem very applicable.

Is it possible you mistyped the link?  I'd like to look into it further.

Yes, this is what I meant.
The key/keyref is a possibility I hadn't explored.

Thanks for the help,
