A knowledge provider maintains descriptions about a large number
of resources, and manages those descriptions in a distributed
manner, such that the sum total knowledge known about a given
resource may be expressed and managed in several distinct
documents, which may be independently retrieved by GET.

A client submits a query/request for a description of a resource
from the knowledge provider, and in response is provided a
complete description of that resource which in no way reflects
the internal, distributed, fragmented content management
infrastructure employed by the knowledge provider.

I.e. clients shouldn't have to know about specific RDF/XML instances,
models, databases, stores, records, or how they are organized,
partitioned, or where located, etc. in order to submit a query of
any kind per the DAWG recommendation.

Queries should be completely agnostic to all aspects of storage
and management of the knowledge in question.

If a knowledge provider wishes to provide explicit access to
a specific body of knowledge as expressed in a specific, single
RDF/XML instance, fine, but that is an implementational detail
of which the client should remain totally ignorant insofar as
the machinery specified by the DAWG recommendation is concerned.
