Talk:Calculated question type

I'm trying to create just a SAMPLE calculated question to evaluate moodle quiz export XML, and am finding it about impossible to figure out. I've done some programming, and have figured some of it, but this is a very unfriendly format explanation. It would be lovely if there could be some explanation as to what a wild card is, and how to create data sets. I can put in a bit about the first thing, but the datasets still have me stumped.

Please explain what a "placeholder" is - there is no other mention anywhere in Moodle (according to search!)

How does it match "item" in the question creation?

A sample would be helpful.
