It's still not very clear to me what any of this means and how it will fit  
together. Having either a specification or examples to shoot at would be  
helpful. Once it is more clear what each of these parts is going to look  
like, it might be easier for me to comment on how you suggest we split

How do you construct a shadow DOM though declaratively without a component?
