Is interface enough to express semantics? (was: [Meta] Confused by the terms)

It is an URL that COULD be associated with semantics.
That's the way we do it with XML DTDs. Like,

    avalon.apache.org/xml/transformer/v1

But, package names are quite url-like. Compare the above to

    org.apache.avalon.xml.transformer.v1.Service

So I don't know what to say here.

Sure SOME interfaces are not descriptive enough to capture semantics,
like java.util.Map.

But others MAY be.

Interface name could even
include a version number.
