I've said this before here, so I don't want to go too deep with this
now, but REST standardizes the interface.  If XML defined common access
to the interface (aka hypermedia affordances)

(across *all* of XML, not just XML with namespaces), the "small pieces,
loosely joined" could be XML.
I reflected a little bit on REST in the piece:

"I’ve also pondered what role REST may play in these conversations. The PUT and DELETE methods are, of course, all about side-effects, and not so much about flow. I don’t yet have a good answer here."

My general sense is that XML+REST is wonderful stuff, but more likely an entry (or exit) point than the communications method used throughout this kind of flow. I would be happy if REST - especially with a hypermedia approach - would be sufficient, but it doesn't quite feel like a neat fit with a pipeline-centric model.

I'm sure it could be made to work, but I'm not sure it should be made to work.

I also have mixed feelings about hypermedia affordances *in* XML. Mostly I'm wary because too many hypermedia conversations seem to reach a point where everyone thinks they agree about what things mean and what things do, and then realize that the agreement isn't that robust.

Roughly, I like the idea, but don't trust myself for liking it.

(I should note that hypermedia conversations were another piece contributing to my sense that this model is coming together for real this time, just not in as direct a way.)
