I am not sure that I understand your question.

To support bus_space_tag_create(9), an architecture's MD
bus_space_tag_t type will change in an MD way.  That is why I say that
bus_space_tag_create(9) is an MI API with an MD implementation.

It may help for you to have a look at the documentation for
pci_chipset_tag_create(9), since bus_space_tag_create(9) works
analogously.  I have not written the corresponding documentation for
bus_space_tag_create(9), sorry.
