+ <para>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.</para>
