Steve, Not sure what you mean by making major changes to the component model. It appears that you mean the deployment API. All of the component model events derive from MUWS. Second, I would like components to use a simple fault model, so I did not include all of the elements of faults that you have done. Also, reflecting Bryan's comments, I made the model a little simpler. Do you really want the deployment API to transmit its own faults as derivatives of the component model? Relaying, sure. But that does not require anything other than WS-Notification support for forwarding of the cmp types.

Some major changes I'd like to suggest to component model 1. every event type extends the muws ManagementEventType . You've done this for lifecycle, but I'm doing it for all deployment events 2. We need to move the deployment fault declarations into the component model, so that your component model can extend them them. The deployment API can then relay cmp: For the xml-cdl schema, is NCName the right choice for component names? There are a lot of unicode chars in that list I propose a name type that can be used in cmp: and api: which is restricted to what we really, really want in the names of things. The system name type I (had) in the deployAPI coudl be the foundation, it said a-zA-Z_\-\. as the first char, the same plus digits everywhere else. I dont know if that is ideal (indeed, I'd drop the "-" from a name, but having a simple, restrictive name type is important. We dont want to repeat the mistake of ant where "," , " " and "" are in fact valid names in some places. <xsd:simpleType name="systemNameType"> <xsd:annotation> <xsd:documentation> This is the policy for the naming of systems </xsd:documentation> </xsd:annotation> <xsd:restriction base="xsd:NCName"> <xsd:pattern value="[a-zA-Z_\-\.][a-zA-Z_\-\.\P{Nd}]*"/> </xsd:restriction> </xsd:simpleType>
