[STACK]/[SERVICE]/metainfo.xml
...
If a component exists in the parent stack and is defined again in the child stack with just a few attributes, are these values just to override the parent's values or the whole component definition is replaced? What about other elements in metainfo.xml -- which rules apply?
...
If a component is missing in the new definition but is present in the parent, does it get inherited?
Generally yes.
Configuration dependencies for the service -- are they overwritten or merged?
