There would seem to be two ways to tackle this kind of issue properly: 1) create a separate spec about MD5 in basic-authentication, and make it standards track. Then it could be reused in every context if free use is granted for standards compliance, or 2) have the service library export only such interfaces that reusing them would not be possible without code modifications and seeing the licensing warning. -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds."
