There is no doubt. I do NOT get classpath.

To confirm: 

The `classpath scheme` is a REQUEST for all file system paths matching the namespace Acme/Demo/Parser . There could be zero matches; could be 1 match; could be many.

Then the noun classpath: "The classpath should be considered the canonical URI for any file." So `classpath` is a NOUN and it defines a specific 1:1 mapping between the namespace and a specific file on the filesystem. 

Questions

1. `classpath scheme` - can that be used with any namespace (ex. a path that does not terminate with a file)? Or, can the scheme only be used with the `classpath` namespace? (Why - what's the purpose? what files are being loooked for? Looking for a use case of sorts just so I can get my head around it.)

2. How does a developer know what the classpath is? Do we need utilities to assist with that determination? Can we expect them to build it into the namespacing?

3. Why "class" -- in other words, does every file have a 'classpath?'  Or, is this only valid for classes? And, what is that suggesting?

4. If so (every file has a 'classpath), is the 'classpath' of the namespace actually the 'absolute path of a file?' (That I can find.)
