> A Tuscany embedder may need to change certain system definitions, e.g. a bindingType or an implementationType.
> System definitions are found using the ServiceDiscovery mechanism.  DefaultDefinitionsExtensionPoint looks for jars/bundles that have a META-INF/services/org.apache.tuscany.sca.definitions.xml.Definitions file.
>             definitionsDeclarations = registry.getServiceDiscovery().getServiceDeclarations(DEFINITIONS_FILE);
> This collects all definitions documents in the runtime.  There is no way to override one definitions document with another.
> I am attaching a patch to address this.  It changes the getServiceDeclarations() call to get declarations in ranked order.  When processing the returned declarations, it now processes only the first resource with a given path.
> The embedder's service declaration must use the same resource name as the Tuscany definition it replaces and it must have a higher ranking attribute.
