There is currently no way to relate a specific setting to a specific settings handlers.. Lets say that a solution (eg. my.application) has two settingsHandlers A and B, and the matchmaker wants to set a setting settingX like so:
There is no way for the system to know whether to apply this setting to settingshandler A or to settingshandler B (currently the system just applies it to both). We somehow need to solve this, probably via an option in the solution registry entry (or rather settingshandler entry) declaring which settings an application supports.
