It seems to me we are not all on the same page with regard to how the profileservice functions in terms of management edits. I'm sorry if this seems to be going backwards, but I want to be clear on how we are all viewing the domain.xml. There are 3 elements:

1. The metadata that drives the deployers to create runtime components.
2. The profileservice admin view of the metadata as described by the ManagedComponents. This is a possibly indirect mapping that allows the deployer/container specific metadata that carries implementation details from a stable admin view that is compatible across releases. Realize that right now we are far from complete in this being a one to one mapping. Only a fraction of the projects have an admin view that is anywhere near complete. The embedded console uses this admin view implicitly by defining its own mapping of ManagedComponent properties onto its UI elements. The push to define a domain.xml is a centralization of the admin view of the metadata. The intention is that this really is the only supported admin interface. Perhaps I have obscured the issue by mentioning that there could be ManagedComponents not in the domain.xml or even properties not in the domain.xml. What is important is that we are defining a complete admin view of the metadata that is decoupled from the deployer metadata. This is our historic problem which manifested as implementation xml files spread out all over in the server deployments.
3. The profileservice implementation which is manages applying admin edits to the admin (domain) metadata view onto the deployer implementation metadata.

Related to Brian's question he started on another summary thread, the first step is to define a sufficient domain.xml metadata model that we accept as our supported admin interface, and evolve that compatibily for each subsequent release. Realize we already have a limited admin domain model that JON supports that is defined by the rhq-plugin.xml mapping between ManagedComponents and the console's supported admin components. We have to step outside of our project metadata models and deal with both the admin metadata view and implementation view. I don't see a limited domain.xml in AS6.0 as a problem because that is in fact the reality. My notion for a minimal domain.xml is one that encapsulates the current embedded JON rhq-plugin.xml model.
