Issue 6353: Deployment a dependency? (uml2-rtf)
Source: NIST (Dr. Conrad Bock, conrad.bock(at)nist.gov)
Nature: Revision
Severity: Significant
Summary: If Artifact and Node are classifiers, why is deployment a dependency?
Then runtime artifacts cannot be deployed to runtime nodes.

Resolution: Disposition:	Deferred to UML 2.4 RTF
Revised Text: 
Actions taken:
October 20, 2003: received issue
Discussion: 
Run-time artifacts can be deployed to runtime models, but the type consistency
is not formally guaranteed (that is, if Artifact A is deployed to Node B, then
instances of A are deployed to instances of B, but there is no ‘instantiation’ of the
deployment relationship).
In order to formalize the instantiation aspect, Deployment would need to be
modeled as a subtype of Association. This solution has been touched on in the
submission process as a simplification and tightening of the model but requires
some time to work out and bed down, as it would be a non-trivial change. Hence,
it would be best tackled in an RTF process. Note (if this solution direction is
accepted) that the notation would need to be changed to not use a dependency,
but rather an association (possibly with keyword <<deploy>>).
