[DDI-SRG] Bug 122 - CodeScheme Editing

[J Gager]

I have looked over this, and it seems very heavy weight for schema. To me it
seems that this is just a matter of creating a new version of a code list,
in which case it is probably best to do this by explicitly recreating the
entire list (not using the code scheme reference). If we are talking about
creating a new code list from an existing code list, shouldn't this be done
with grouping. It almost seems that we should get rid of the code list
reference altogether and leave it all to our grouping mechanism. I think the
same could be said for all schemes. We should avoid having multiple ways to
do the same thing.

That being said, feel free to tell me that these are not the same thing...
