Any word in all-caps is 'converted' to small-caps. This behaviour can be changed, or even disabled, by setting a flag in the options object before processing. I prefer to keep all-caps out of my body text.
Back at Flipboard, for our RSS typography processing, we used a rule of thumb that all-capped words 3 letters or longer would get small-caps treatment. It worked pretty well.
