Thread:Extension talk:TemplateData/Inheritance

Can TemplateData be inherited from one template to another?

This would be useful for templates which include other templates. For example, on Commons we have commons:Template:Art Photo which is commons:Template:Artwork + commons:Template:Photograph, passing along the values to these templates. It is really annoying to duplicate the TemplateData from one to the other, and to keep both in sync.

Thanks,
