Re: [ubl-lcsc] [ubl-ndrsc][ubl-lcsc] Versioning, Extension and Header Containers

| Unless we have Header containers of some sort, we will have to add any
| additional elements to header containers at the end of the document in
| subsequent minor versions.  A similar phenomenon applies to extension -
| if anyone wants to extend our set of "header" elements, the additions
| will go after the body items.

This looks like a pretty big problem.  Is it on the agenda for
discussion this week?
