Query on Figure 3-1

["CRAWFORD, Mark" <MCRAWFORD@lmi.org>]

Folks,

The attached figure was originally created in SF last November.  There was never any supportive text.  In trying to write the text, I have come across a roadblock.  Specifically, for the box labeled SchemaModule, that is pointed to by InternalSchemaModule and ExternalSchemaModule and in turn points to W3C XML Schema, what does this represent.  I really don't recall what its purpose was, why it was split between the DocumentSchema namespace and external namespaces.  Any help would be appreciated.
