// This is a mix-in class which handles the enabling policy for
// CPaneEnabler.
//
// For an object to be enabled by a CPaneEnabler attachment, it should
// mix-in and implement this interface. Note that a default policy is
// implemented by CPaneEnabler. This is intended for LControl and LPane
// derived classes which cannot be changed to mix-in MPaneEnablerPolicy and for
// which the default policy in CPaneEnabler already Does The Right Thing<6E>.
