The numbers aren't independent at all. Don't try to make the library 
interface version components into a software revision number. The scheme 
is the way it is because the OS library loader uses the values in these 
fields to determine if a particular library will support a particular 
interface request. When a program attempts to load a library versioned 
1.0.0, but the OS loader can only find 2.0.1, then the loader will go 
ahead and load 2.0.1 because the '1' in the age field indicates that 
this library supports 1.x interfaces as well as 2.x.

Jan answers the rest of your question in his response.
