updating specs

[SylvainTakerkart]

Hi!

On the online docs, there are a few things to fix:

• the very first sentence (we can remove or modify "this is the very first draft...")
• the sub-subName (and the other equivalent names at the different levels of the hierarchy) in the figure, which should be sub-GUID (it should be strictly the same as in the specs)
• there should be a link with the github developer's andochecker url etc.

Hi ! I have made some changes as asked above :

• [x] the very first sentence (we can remove or modify "this is the very first draft...")

• [x] the sub-subName (and the other equivalent names at the different levels of the hierarchy) in the figure, which should be sub-GUID (it should be strictly the same as in the specs)

• [x] there should be a link with the github developer's andochecker url
