[CF-metadata] PID to external description of Quality and Status states

Dear list,

A CF-conformal NetCDF file should be as self-describing as possible.
URIs/PIDs poitining to external data sources are problematic in this
context. However, IDs pointing to external data sources were already
discussed for taxa in the CF Trac Ticket #99 "Taxon Names and
Identifiers" (https://cf-trac.llnl.gov/trac/ticket/99).

Let's assume we have a long description of quality control measures
performed resulting in N possible quality states for a NetCDF variable.
The full description could be part of a peer-reviewed paper or grey
literature (with assigned PID). However, it is too long to be included
in the attribute "description" of the quality/status flag variable. One
solution would be to add a brief description of the quality states to
the quality_flag/status_flag variable and point to the external full
description via it's PID.

What is your opinion on this?

This is not a request for a feature but rather meant to collect some
opinions on this topic. It is somehow related to the request of a global
PID attribute in CF GitHub Issue 160 "Add attribute citation_id"
(https://github.com/cf-convention/cf-conventions/issues/160).

Regards,
Daniel
