Are we suggesting that the various "parts" are a single document within
the computing environment of the client or server? Mais non. However,
they are part of a single "document" on the wire. Whether to describe
representational types with a WSDL-specific EII or to re-use XML Schema
is an engineering decision not a modeling issue.

(Such healthy discussion! It's so much nicer than mere administrivia.)
