What does an SCA Assembly look like?

Here's a picture of an SCA composite, as found in the SCA Assembly specification.

What do you think? Pukka or pants? Personally, I think it's a bit inclined to the trousers side of the question. We all worked on the specification words, which were scrutinized most closely, but the diagrammatic representations didn't get much attention. Perhaps we are looking here at an interface designed by Engineers.

One of the things on the STP project plan is a graphical editor for constructing SCA composites from pre-existing service elements and allowing the compositor to wire up the various components and eventually package and deploy it to an SCA runtime. I'd like it to be a useful representation, however, and not something as clunky as what you see here. I know that many of you software developers are really frustrated designers at heart - what's your opinion?
