YES/NO: Are the UnitMemberTemplates.xml art defines usable for mods?

[Eltoshan]

assets -> Units -> Civ5ArtDefines_UnitMemberTemplates.xml

This has art defines for templates, like a single unit mounted model or a single warrior rather than a group of them.

Are these defines usable? Like, SHOULD this work? Or am I missing something (because obviously it is not currently working)?:
