NEW ISSUE: @Callback and @Remotable on implementation classes

TARGET: Java Common Annotations and APIs

DESCRIPTION: @Callback and @Remotable on implementation classes

It isn't clear whether the @Callback and @Remotable annotations
can be applied to service implementation classes.

An SCA service can be specified as either a Java interface or
a Java class.  (See the definition of @Service.)

The description of @Callback says that it is used to annotate
a service interface.  It isn't clear whether this is an SCA
service interface (i.e., a Java interface or a Java class),
or only a Java interface.

The description of @Remotable says that it is used to specify
a Java service interface as remotable.  It isn't clear whether
this is an SCA service interface written using Java (i.e., a
Java interface or a Java class), or only a Java interface.

PROPOSAL:

For both @Callback and @Remotable, change the description to
say explicitly that these can be applied to Java classes.
