Quoted from the referenced link:

"The From request-header field, if given, SHOULD contain an Internet
e-mail address for the human user who controls the requesting user
agent." [...]

Clearly an identifier, not a physical endpoint.

And:

Indeed.

So, shouldn't wsa:From be simply a URI, rather than an EPR? And
having used such a syntax, shouldn't we imbue it also with the
semantics of an identifier, in a manner similar to that of the above-
referenced section of RFC2616?
