Re: [netmod] Adoption Poll: draft-rtgyangdt-netmod-module-tags-02

Hi,

In the light of this discussion, I would like to clarify that my
support is for the problem of tagging *modules*, which I believe this
draft is all about.  I don't think we should extend this to tagging
*nodes*; I think that requires a different mechanism.
