Hi Peter,

It actually is and I realise that we did a pretty poor job in handling your review. Sorry for that.

In order to progress, let me propose a incremental approach:

Hereafter I put and comment everything that is minor issues. 
Let me know if you are OK.

Once we clear them we will go to the beefy stuff (aka major issues).

What about the following text:

	This document proposes a framework for the management of the
 	LISP EID Address Block. The framework described relies on hierarchical 
	distribution of the address space, granting temporary usage of prefixes of
        such space to requesting organizations.

Fair enough. This was a degree of freedom we left to IANA. The requirement is globally uniqueness, 
how IANA, registries, or anybody else running the “Registry" want to sync to respect the requirement 
is something left as “implementation specific”.

My personal take on this point is that since the experiment has a limited duration and 
because it is very likely that the only registry running the service will be RIPE NCC, 
there is no need to over-engineer this point.

Thanks, will be fixed in -07.

Thanks, will be fixed in -07.

Does not apply anymore.

This is already fixed in -06.

It does not harm actually. Will be added in -07.

Thanks, will be fixed in -07.

This is already fixed in -06.

We are now at -12 and will keep the reference updated.

This is a fair point and it has been raised also by other. 
Let me answer in the same way: What is the arm in having such appendix?
- It is an appendix so its content is clearly optional.
- It clearly spells out that is not normative content but only to avoid the reader digging around to find the definitions.
- Some readers that do not know LISP might find it handy to have it around.
