What does /!/ mean in C#?

I have been poking around in the IronPython 2.6 source code and noticed that the comment /!/ appears often. Example in ArrayGlobalAllocator.cs:

public ArrayGlobalAllocator(PythonContext/*!*/ context) {

It doesn't seem very informative, so I guess it has a predefined (or agreed upon) meaning? What does it mean / what is the purpose?

Thank you.
