Agree about sca-contribution.xml not being simplest nor META-INF/deployables, but we've had this discussion before and couldn't get much agreement on anything else. Take the Tuscany/Geronimo integration as an example, deploying an sca contribution jar on that and the code can only tell which composites to add based on somethng like sca-contribution.xml or doing some default behaviour like add all composites or add no composites. Does the spec say anywhere that when there is no sca-contribution.xml then composites in a contribution must not be added by default? ...ant
