-------------------------------------------------------------
IsComposable="true" explicitly allows adding path segments, key predicates, or
system query options, here the revised text from Errata03 (currently in
document production):
> A composable function can be invoked with additional path segments or key
> predicates appended to the path that
> identifies the composable function, and with system query options as
> appropriate for the type returned by the
> composable function.
IsComposable="false" only means that there's no guarantee that a client can add
these URL parts, "false" does not forbid to add these. So IsComposable should
not have any influence on the behavior of the library, it's just an attribute
in $metadata.
