One example of an interoperability workflow might be: A software vendor that utilizes custom derivation paths in their schemes create a "profile" that contains the constraints on the paths (and possibly other parameters, but this is out of scope of the proposal) for their particular scheme. In a simple case it might just be a path template string provided in the documentation. A user of a software solution from that vendor takes a hardware wallet that supports path templates (or richer "profiles") and installs the profile for that solution into hardware wallet. In a simple case, the user just pastes a path template string into some configuration utility program and then confirms the setting on-device. The device statrts to enforce the constraints specified in the template (or "profile"), and the software solution works as intended by the software vendor.
