Further, instead of packaging Web Components into one omnibus
offering, we will likely end up with several free-standing specs or
spec addendums:
1) Shadow DOM, the largest bag of with XBL2's donated organs --
probably its own spec;
2) Constructible and extensible DOM objects which should probably
just be part of DOM Core and HTML;
3) Declarative syntax for gluing the first 2 parts together -- HTML
spec seems like a good fit; and
4) Confinement primitives, which is platformization of the lessons
learned from Caja (http://code.google.com/p/google-caja/), integrated
with element registration.
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
them.
Why split it like this? Several reasons:
a) they are independently moving parts. For example, just shadow DOM,
all by itself, is already a useful tool in the hands of Web
developers. It's our job as spec developers to ensure that these bits
comprise a coherent whole, but from implementation perspective, they
don't need to block one another.
How do you construct a shadow DOM though declaratively without a component?
b) each belongs in the right place. For example, making DOM objects
extensible is a concern inside of the DOM Core spec. Declarative
syntax really needs to live in HTML. Also...
c) some parts are too small to be their own spec.
Constructible/extensible DOM objects bit does not even have an API
surface.
d) And finally, every bit has potential of solving problems that are
more general than just about components. We shouldn't require making a
component if all developer wants is some shadow DOM. Similarly, lack
of needing a component shouldn't preclude the use of confinement
primitives.
Just to recap: XBL2 is dead, exploding into a pretty rainbow. I am a
pop tart cat in front of the rainbow.
