Yes the implementations follows the spec and as such only supports the elements defined by the spec.

Yes, this is how the Configuration Admin specs states it: The ConfigurationAdmin.createFactoryConfiguration methods generate a unique PID automatically. There is no way to predefine it. It just so happens as an implementation detail, that the Felix implementation does it like this. > > Also, is there some discussion groups where future specifications are > discussed? AFAICT There are discussions in the OSGi Alliance to update Configuration Admin. One idea is the notion of a Configurable (see Peter's blog on this subject) where a configuration object is created ORM-style from the configuration data. This will for sure have an influence on other related specs like for example MetaType service or Declarative Services. Regards Felix > > Thanks in advance > BR > -- > Ing.
