Re: proposal for "Content" class

Hi,

Following the latest discussion regarding sequences [1], and the recent 
proposal by Johannes [2], please find an updated proposal for the RDFS 
attached. The only difference to the previous version is a restriction 
that every HTTPContent class must have *exactly one* httpRequest and 
httpResponse pair.

Regards,
