New obsolescence reason specification

[FernandaFarinelli]

I'm normalizing some of ONTONEO PURLs and the better option is to turn obsolete some ids and replace by new ones.
So, in this sense, I need to annotated my obsolete properties ids with obsolescence reason.
However, my view, the reason to obsolescence is none of such list: "failed exploratory term", "placeholder removed", "term imported", "term split", "terms merged".
I think the best obsolescence reason in such a case is "Normalize PURLs" or some more generic such as "Curation of ontology specification/elements".
May you can add this new obsolescence reason in IAO? Or, orient me in an alternative way to annotate my obsolete property.
Thank you,
Fernanda Farinelli
