Yes exactly. in this case, value[2] > foo/Echo/echo. As I explained above,
after checking for foo, it tries to find a hierarchical service from
foo/Echo/echo. If that is also not found, if tries to find a hierarchical
service foo/Echo with the operation 'echo'.

Yes exactly. That can be done. We can use some other charactor like '-' to
represent '/' charactors in the service name. That will avoid most of the
logics I've added to properly handle this. I can resend a pathc using '-' if
we can agree on that.

Yes if the servnce name is version and we have services/version.aar and
something like services/version/1.0.0/version.aar, it will cause a problem.
But that is a limitation with which the user have to live with, if he wants
to use hierarchical services. Otherwise he can use the way we have right
now.
