Open Standards

Paul Fremantle: For me the core difference between Open Standards and Open Source is this: Open Standards enable companies to compete in a structured way, Open Source projects enable people or companies to collaborate in a structured way

I think Paul may be onto something.  It is rapidly becoming the case that this more than this is becoming the exemplar for open standards.  While it is popular to malign the JCP, it is worth noting that many (most?) JSRs have TCKs which actively promote the idea of multiple, independent, interoperable implementations.
