Bertrand Meyer on IDL, components, etc..

Here <http://eiffel.com/doc/manuals/technology/bmarticles/sd/dotnet.html>
is an interesting article by the father of Eiffel, Bertrand Meyer, on
some issues we talked about last sunday in Pisa: the shortcomings of
CORBA's IDL as a good component interfacing and documentation
language; and the distinction between a ``Service Request Broker'' and
an ``Object Request Broker''. The former can work with a `meta-data'
description of a component's interface, without the need of a specific
(IDL) syntax.
Especially the section on ``Documenting components'' (with
the remarks on the advantages of meta-data with respect to IDL) is
relevant to the current state of Orocos: we have to define how we will
specify and document the interfaces of our components. And maybe we
can profit from the Mono (<www.go-mono.com>)/.NET lessons in this
respect... Does somebody has a good pointer to documentation about the
state of affairs about these matters in Mono?
