To answer the question correctly, I need to know what you want to happen 
for people who have the subpackage installed currently.

If the package is replaced or superseded by a different package (so 
sub_package should get uninstalled, and replacement_package installed 
instead), just write:

replacement_package_OBSOLETES="sub_package"

If the package is really being removed without any replacement, there 
are mechanisms to deal with that case, but that case should be really rare.

Generally, you never want to do this, at it means the current version 
will linger, remaining installed (potentially with (currently 
unreported) file conflicts with any replacement).
