Can Divine Elements be further subdivided?

[Coinage]

Hello

I just picked up a version of Pyramid 4-4, and I was reading the article on Divine Elements. I was also reviewing the concept of Divine Domains in the rpg Pathfinder, and I discovered the concept of Subdomains (found here), where Divine Domains are further divided into specializations called Subdomains. For example The Air Domain, can be further subdivided into 3 Subdomains: Cloud, Lightning, Wind.

Is it possible to further subdivide Divine Elements? Just curious.
