<iframe> and <object> at least.

I don't think so. In existing uses @name names a context

Not perfectly fine, I think, because the attribute named @name already 
has a defined purpose ame everywhere and it identifies something 
different than a track of a video.

OK, @name is already used in elements of the same class, if class 
means a category like embedded content.

Same requirements and best practice for all elements/attributes, I 
think. Are there other examples where the same string is used for 
attributes that carry different information?

@name. That interface deals with element names, not atributte name.

All in all, existing usage of @name in elements is not crystal clear 
except it appears @name can be used to access an iframe element or 
object by script. same or similar to @id. .
