Hello all, The following 2 sections talk about package extension. 6.2.3 Packages For improved interoperability and backward compatibility, an MG MAY publish all Packages supported by its Terminations, including base Packages from which extended Packages are derived. An exception to this is in cases where the base packages are expressly "Designed to be extended only". 12.1.1 Designed to be extended only (Optional): Yes This indicates that the package has been expressly designed to be extended by others, not to be directly referenced. For example, the package may not have any function on its own or be nonsensical on its own. The MG SHOULD NOT publish this PackageID when reporting packages. I think there could be a chance that some people misread section 6.2.3 in that "Designed to be extended only" packages MAY be published. I believe this is not the intention as clarified in section 12.1.1. Therefore I would propose that 6.2.3 states: 6.2.3 Packages .. For improved interoperability and backward compatibility, an MG MAY publish all Packages supported by its Terminations, including base Packages from which extended Packages are derived. An exception to this is in cases where the base packages are expressly "Designed to be extended only"<<<, these packages shall not be published.>>> Regards, Christian
