> DESCRIPTION: Possible confusion over whether @Service can specify both
a
> class and an interface
> 
> Lines 91/92 contain the following sentence:
> 
>   The Java implementation class itself, as opposed to an interface,
>   can also define a service offered by a component.
> 
> The wording of this sentence could possibly be taken as implying
> that an implementation can provide an SCA service defined by the
> implementation class only if it does not provide any SCA services
> defined by an interface.
> 
> It is my understanding that an implementation can have a mixture
> of class-defined services and interface-defined services.
> The definition of @Service in JavaCAA says that @Service can specify
> an array of interface or class objects.  This implies to me that a
> combination of these is OK.
> 
> Assuming this interpretation of JavaCAA is correct, the above
> quoted sentence in JavaCI is confusing.  The troublesome phrase
> is "as opposed to an interface".  This could be taken as saying
> that if a class is used for the service definition, an interface
> cannot be used in addition.
> 
> PROPOSAL:
> 
> Replace the above quoted sentence by:
> 
>   Another possibility is to use the Java implementation class itself
>   to define a service offered by a component.
