I assume people mean UML class diagrams when they say UML. That said,
yes tools can turn UML into other stuff. However, whether the result
is 'nice' or 'implementable are reasonable pain' is a different
question (and I understand that 'nice' and 'pain' have no clear
definition). UML class diagrams allow the representation of arbitrary
relationships between classes. If you have to turn this into a
hierarchy for a protocol using a hierarchical namespace, then tools
most likely only create _a_ solution not a _good_ solution.

If you believe tools do a good job translating IMs to DMs, you will
likely soon find that this is generally not the case and in order to
make it work better you will start to augment you IM with lots of
additional detail for the translator to do a reasonably good job, in
which case your IM deteriorates to some extend into a DM.
