I was looking at possibility of representing tags/keywords/codes https://sarcontacts.info/glossary/ (for #3052) in a lightweight and semi-structured manner in Organization and ContactPoint markup, ... and realized that we currently have no text-valued field on Organization suited to carrying such data. This seems an easy fix. We can also consider Event, Product, Place at least.

Currently:

Keywords or tags used to describe this content. Multiple entries in a keywords list are typically delimited by commas.

Proposed:

Keywords or tags used to describe this item. Multiple entries in a keywords list are typically delimited by commas. The keywords property can also be repeated to avoid confusion if multi-word phrases are used and contain commas.
