Hi Monika,

I did not actually mean matchmaking based on keywords, but a way for the profile
to be more expressive and more near what a user would request from his agent.
One should not think of a service by its I/Os only. It does not make sense from
a user perspective to define a request to his agent which includes AccountName,
Password or any other input or output(how will these be known before hand?).
The profile should present features related to its usability, what is the nature
of the service, what solution can it provide. Eventually if the user/or his
agent are satisfied with these issues including other service parameters, then
the I/Os can be considered.
