I think what you mean here are stylesheets for the diagram, and a way
to "tag" objects.

Stylesheets can be extremely useful ... for example, I use each
diagram in two contexts ... in a LaTeX report, and in the accompanying
presentation. Every time I reuse a diagram from the report in the
presentation, I have to open it up in Emacs and mass replace all
colours. I usually am careful enough to assign colours in such a
manner that there is a one-one correspondence between classes and
colours used for them, which is useful when replacing text in the Dia
XML file.

As far as I can see, all this is definitely Dia 2.0 stuff, though! :)
