XMI11 — Multiple Inheritance hard to handle in XMI

Summary: THe background it is the use of XMI for interchange of warehouse
information. The person prototyping
the exchange is Brain Volpi so if you have follow on questions, please
copy him since I am on vacation for the next two weeks.

1. We are using UML to define the meta models and the created the DTD"s
and document streams.

• our model contains multiple inheritance which is hard to handle
  in XMI. Does anyone have any
  comments or suggestion on the mapping to XMI we should consider.

• our model contains UML interface definitions which we have mapped
  into abstract classes
  any comments on a better way to do this?
• UML has ordered associations and we are currently assuming the
  XMI stream will always be
  in the correct order. Is this valid?
