Len, I always greatly appreciate your informative, philosophical, and
humorous comments.  Let me see if I can elaborate on (my) purpose of the

Yes, this is an attempt to influence how web services will be designed
and the nature of XML messages.  I am very concerned that people will
use web services simply as another way to do tightly coupled RPC, i.e.,
procedure name plus parameters.  I think that XML-based web services
should provide a new paradigm, where the focus is on the data and
business processes.  I think that this involves a rather large mental
shift, from this mentality: 

- call this routine with these parameters, get these results back, 

to this mentality:

- here's business data, let me find one or more services that can
operate on the data.

I am looking/searching for a paradigm which will FORCE developers to
make that mental shift.  I have a gut feeling that requiring the
separation of the data from the action will be such a driving force. 
Developers are quite comfortable with colocating data and actions. 
Forcing them to separate the two, and thus focus on the data and
business processes will result in a quantum design/mental shift (IMHO). 
That's my ultimate objective.

Now back to the issue at hand ..  I take it from your comments that you
question the role of multiple actions?  /Roger
