Sounds like an oxymoron, doesn't it? Is it a standard or is it a guideline? It's both, and it's courtesy of the ISO/IEC JTC (joint technical committee). I've been told the new document was created from a SWGDE guideline, but since you have to purchase the "standard" I couldn't really even tell you what language it is in, because I'm not paying for any document created in a vacuum.
