ahahah :))) Remember my first graph? ;) It was what I have designed the 
first time and you said there was a need for a core module ;) not me. 
:)
For me level 1 encompasses all the module that you need to implement 
it's a kind of defining the Basic Conformance. :)))

I would prefer to call out the module A and B because they can be 
functional division of the technology.

	Module Text
	Module Table
Part of Level 1 and Mandatory for conforming implementation
Though someone outside may need just one module for a precise task.
or for a developer it might make more sense to map a program on the 
functional division.

	Yes the arrow to the Level 1 is not necessary.
		I will explain under the graph that Level 2 includes Level 1.

	Do you think it's acceptable to implement half of a level?
	It would mean that Profile X is just Level 1 conforming application 
plus things Module C and an optional module E?

Hmmm not sure. I would rather make an evolving diagram.

1. Modules + Levels
2. Diagram 1 + Profiles on top
