An implementation of a Specification: (i) must fully implement the Specification including all its required interfaces and functionality; (ii) must not modify, subset, superset or otherwise extend the OSGi Name Space, or include any public or protected packages, classes, Java interfaces, fields or methods within the OSGi Name Space other than those required and authorized by the Specification. An implementation that does not satisfy limitations (i)-(ii) is not considered an implementation of the Specification and must not be described as an implementation of the Specification. "OSGi Name Space" shall mean the public class or interface declarations whose names begin with "org.osgi" or any recognized successors or replacements thereof. An implementation of a Specification must not claim to be a compatible implementation of the Specification unless it passes the Technology Compatibility Kit ("TCK") for the Specification.
