Hi Mark, Thanks very much for the references.
I am sorry if I wasn't clear in the paragraph you reference. I was trying to draw a distinction between the definition of an architectural style (such as SOA) and a concrete protocol specification (such as HTTP). An architectural style is not a technology - meaning that the definition of the style is distinct from its implementation in any particular technology. I believe for example REST is not the same as HTTP, the former being the architectural style and the latter being the technology which most closely implements the style. Sometimes it seems like confusion still exists between the two, and sometimes it seems like confusion still exists between an SOA and the technology that can be used to implement one.
