> Stereotype declarations are transitive. However, the spec is not clear what happens if a stereotype declares a default scope and also a second stereotype which also declares a default scope. Only _"If a stereotype declares more than one scope, the container automatically detects the problem and treats it as a definition error."_ is defined.
>  
> Weld currently does merge the stereotypes and throws {{DefinitionException}} if NOT all stereotypes specify the same scope _and_ the bean does NOT declare a scope (this makes sense imho).
> Note that this is not a problem for {{@Named}}, {{@Alternative}} and interceptor bindings.
> Any {{@Alternative}} makes a bean an alternative. Any {{@Named}} means the name is defaulted. All bindings are added to the set.
