At least, that was what it was like the last time I researched it.
Technically is 90 days in a 180 day period, which is an important qualifier. You can't leave for a day on day 90 and come back and reset the clock, you'd have to wait another 90 days to return.
As for the rest, pretty much, with a whole lot of "yes, but..." qualifiers. For example, Aussies, Americans, Canadians and a handful of others are allowed an extra 90 days in Denmark, regardless of having already spent 90 days in the Schengen zone. The opposite is not true, you cannot spend 90 days in Denmark and then leave to other Schengen zones.

Likewise, I've met a few Kiwis in Europe, apparently they have quite a few countries that allow individual state clocks that operate in place of the Schengen rules due to grandfathered visa arrangements that predate Schengen. As always, it is best if you know the rules for your nationality and destinations.
