Hi Roy and Julian, thanks for the replies.

The specific text which confuses me, from the section on weak validators, is (emphasis mine):

"However, two simultaneous representations might share the same *strong* validator if they differ only in the representation metadata, such as when two different media types are available for the same representation data."

Am I misunderstanding that this is in conflict with the example you gave?  (text/plain and application/json representations with same octets must have different strong validators.)

Similarly:

"Likewise, a validator is weak if it is shared by two or more representations of a given resource at the same time, unless those representations have identical representation data."

The "unless" clause would appear to apply to the example you gave, implying that both representations can have the same validator but need not be weak.

Thanks, Chris
