+1. A URI is an Identifier, which is not necessarily a Location.

The spec doesn't use the term "physical address".  Or "logical address"
for that matter.  The WG had rather extensive discussions about this
topic and had in the end to steer clear of defining wsa:Address as one
or the other.

AIUI, an implementation is free to use the value of the [address]
property in the underlying transport (e.g. the HTTP address when using
SOAP/HTTP), but is not required to do so.  The client may instead route
the message to a proxy, an intermediary, or perform a catalog lookup -
all well-known infrastructure for delivering a message correctly to a
final recipient.  Each mechanism provides value-add to the message
delivery path (security, robustness, better performance, etc.)
