Taxonomy and Variables

I have a variable set (version) in my site.yaml to specify the content version, and I would like to use that variable in my taxonomy, but I am getting an error. Is this possible?

title: Introduction
	category: ['docs']
	effective: ['in-effect']
	audience: ['general-users']
  	version: {{site.version}}

@crusnac, AFAIK, Twig expressions in taxonomy values do not get parsed.
