Re: ISO 9002:1994 to ISO 9001:2000 conversion (transition)
It's not "whatever else you want"; it's whatever else is necessary. On top of that, you can have whatever else you want, but if "whatever else" is a documented part of your QMS, it's auditable, notwithstanding the requirements of the standard. The whole idea behind the Big Six is to say, "Here's what's absolutely mandatory--the foundation of the QMS," and the implementation is expected to include documents and processes needed by a specific business to support the system. I reiterate--the standard doesn't say that only six documents are necessary. As you point out, records (e.g.) are a type of document, and some are mandatory, such as records of contract review and management review. Where processes have been established in support of the QMS, it's expected that they'll be documented as well. The documentation produced will expand in direct proportion to the degree of pedantry and legalism invoked in interpretation of the standard (can I call this Wynne's Law?). Less is more, so long as the requirements are met, and the resulting system is efficacious.
I can't account for the opinions of auditors, but I doubt that if I documented any process that I felt was important to the operation of the system that I would allow any auditor to shut it down.
Not "frail." Lean. 
I do like your additional discussion but rather favor my interpretation. Even if ISO is saying you must have these six plus whatever else you want would they actually leave out Management Review, Competence/Awareness & Training, Maintenance, Quality Planning, Contract Review and even the one they name a process - Purchasing, in favor of what documents you need to issue and how do you control records? Without some of those in 5, 6 & 7 you don't even have a system.
Then, I have produced process maps that included 4.2.3 and 4.2.4 as prcesses and got shut down big time by two individually independent registrars. Yet, they are both members of the six "Documented documents (processes) you refer to.
I don't know Jim, sounds just a bit frail - don't you think?

just kidding.
