XML Schema defines the concepts of minimally-conforming processor; a=20
fully-conforming processor; and a processor "in conformance to the XML=20
Representation of Schemas".

 Perhaps something similar could apply here. It is also interesting to no=
that in XML Schema, the essential difference between being "in conformanc=
e to=20
the XML Representation of Schemas" and being "fully conforming" is=20
"network-awareness" (in this case being capable of retrieving schemas for=
validation purposes), which raises the issue of processing of external=20
topicRefs - perhaps a minimally-conforming processor could also be exempt=
from chasing down those references ?

Minimally conforming processor: Implements the SAM w/o TNC and does not=20
retrieve an entire external topic map resource when encountering a refere=
to a topic in another topic map.

In conformance to the TNC: Minimally-conforming + TNC

Fully-conforming: In conformance to the TNC + retrieves external topic ma=
resources when encountering a reference to a topic in that external resou=

If nothing else, it adds another level of differentiation for the vendors=
! ;-)

Just a thought...
