A document does not need to define a syntax in order to be useful.
For
instance, a document containing sections such as this could be good and
useful: "The following regexp allows all classic email addresses and
disallows many common typing mistakes...", ditto EAI, and with
descriptions of their shortcomings.
I am not sure whether something
that matches a subset of valid addresses could be useful.
Perhaps.
