That makes sense and that's where I looked first.  However I didn't find 
the faculty to load a proto / pb.go file in that library.

As far as I can tell the intention of dynamicpb is to be able to create 
dynamic messages, I don't see the faculty for loading a fileDescriptor from 
a proto / pb.go file in that library.

Where in the API (for any language) is the call to load a descriptor 
dynamically?  

I'm looking here right 
now: 
https://pkg.go.dev/google.golang.org/protobuf/reflect/protoregistry#Files.RegisterFile
 
and wondering if this is the method I'd be looking for.

Thank you for taking the time to reply!
