Thanks Lee, I've take this as a base and then tweak it a bit, does this read OK?
/**
* This is a set of bits (flags) that represent the Node.
* The default value is 0xffffffff (all bits set).
*
* The most common use of these is during traversal of the scene graph.
* For instance, when traversing the scene graph the
osg::NodeVisitor does a logical
* AND of its TraversalMask with the NodeMask here to
* determine if the Node should be processed/traversed.
*
* For example, if a Node has a NodeMask value
* of 0x02 (only 2nd bit set) and the osg::Camera has a
CullMask of 0x4 (2nd bit not set) then during cull traversal
* (that takes it's TraversalMask from the Camera's CullMask)
the node and any children would be ignored. Conversely, if the
osg::Camera CullMask were 0x3 (2nd bit set) the node
* would be processed and child Nodes would be examined.

If my build completes successfully I'll check the above in,
Robert.
