A - V1.1 and V1.0 completely separate

B - V1.1 and V1.0 composite in the same domain

B-1 Just running in the same domain

Need both types of processors and a shared model. With separate nodes, v1.0 and v1.1 runtimes could be seaprated. Doesn't seem to be much advantage over independent operation

B-2 Running and interacting in the same domain

Need both types of processors and a shared model. With separate nodes, v1.0 and v1.1 runtimes could be separated. Need an interoperable binding.sca (we have this at the moment as it is based on binding.ws)

Handling both v1.1 and v1.0 policies

Need policies in both namespaces represented. Create side by side defintions.xml files in extensions?

C V1.1 component implemented using V1.0 composite

Need both types of processors and a shared model. Need a shared runtime, i.e. some flexibility in builders, pluggable conversations and callbacks. Not sure about activation.

D V1.1 implemented using implementation.osoa (or similar)
