I worry about this way of specializing properties. How are people, and particularly programs, going to be able to find out that a qualifier is needed, which qualifier it is, and how it is to be used, or which broad property is to be used for a specific purpose?
This problem exists either way: either you have to know which specific property to use, or you have to know how to qualify the broader property. In both cases, human readable documentation is the way to find out.
