Relevance / use of Document Category codes for CSOs


I’d like to understand whether the existing DocumentCategory codes are of relevance/use to CSO publishers. Specifically, the codes that begin with A (applicable to Activities) :

Context - I’ve been working with these documents : - there is no direct mention of Logframe, Final Report and Proposal in the A-type categories, for example - meaning some interpretation is needed.

Has anyone made a mapping?
Should clarification text be created/added to the existing codes?
Is there a pressing need for new codes?

Whilst I have posted this in the CSO category, this might be applicable to other users. @johnadams might have ideas…
