Subject: SERCOS Interoperability

I am getting confused about SERCOS interoperability.
Some people seem to say that as long as a drive has a SERCOS interface, it can be used with any control device (with a SERCOS interface of course). And that you can mix various drives from various manufacturers on a single SERCOS loop.
But some people say that although SERCOS is a standard, there are many optional features that some drives have or have not, and that certain controls cater for or not. If this is the case, you probably can't simply mix and match various drives from various manufacturers.
And what does class A or B or C conformity mean ? Which again seems to indicate that all SERCOS drives are not equal (or is it just something to do on the control side ?).
So what's the real story ? Anybody has experience on this issue ?
