 From the perspective of the SOAP module the attachments are
resources.  That is why we use URIs to name them.

 From the perspective of the packaging module the attachments
are representations.  It deals with bytes.

The confusing concept from the Web point of view is "Compound
SOAP structure".  This programming construct cannot be
precisely defined: it may contain pointers that are not bound.  A
compound SOAP structure is a logically a "view" rather than a
physical region of memory or a packet of data.  The construct
that can be defined is the message package.  That is why writing
the spec for the package is easier that defining how the package
looks from the SOAP layer.
