Cert 3.x -- We need a better way of representing "one of" in cert req's

[ViktorHaag]

Some of the metric profiles require nothing be provided for certification, and this is clearly not what's desired (i.e. all the items in the Assessment Profile are Optional).

We could address this by having three requirement phrases, not two:

• "Required": must always be demonstrated to qualify.
• "Optional": may be present, but no need to demonstrate to qualify.
• "[One|Two|Three] of": Of the rows marked this way, must demonstrate that number in the set so marked to qualify (so in a table where four rows are marked "Two of", you must show two of those four to qualify for certification).

I suspect these rules would be flexible enough to encode all the possibilities we need (and if they can't then I suspect our needs are too complex). The last rule is tricky, but could be explained fairly simply on how it works (note that we could have tables that have both "one of" and "two of" rows, if we really wanted to be complicated, but I don't expect we'll see that, really...).

Never mind -- I misread Assessment Profile; it does have a (single) Required row. We might want to consider this change anyway to give us a bit more flexibility in how we can enforce coverage for certification purposes...

We already do something similar to this (see Feedback Profile). Closing as no need to fix.
