I don't have a strong feeling on this one, but I would tend toward an
approach that embedded SVG with the model using namespaces.

The advantage of using a diagram model such as Gentleware et al propose
is that you can leverage MOF/EMF to get both XMI for your domain model
and for the diagram model (EMF then allows these parts to be stored in
the one document or split between documents (Resources)).

The downside is that a real diagram has a lot more than just boxes and
lines, nodes and edges -- there's text (with fonts and styling),
connectedness of lines and possibly shapes, containment (grouping),
shading, etc etc. Do we really want yet another standard defining all
these things?
