Lite/Full split: decide on "Inter-module injection in CDI Full"

[Ladicek]

The "Inter-module injection in CDI Full" chapter in the specification has a TODO for deciding whether the chapter should extend rules from CDI Lite and add few more (current state, somewhat hard to read), or completely override the CDI Lite rules (would require some duplication, but might be easier to read).
