Well, it will be actually -12 (we change the version # last thing), but we hope so too.  We will post a new version once we come up with good answer to Benoit’s DISCUSS.

I staged this earlier to address this:

It refers to an explicit field name there, as it is “H(Node Data) field” in the two references there. So for now leaving the meaning of that H() to where it is described (which is section 7). If this notation is distracting, we can rename the field to e.g. Node Data Hash field and describe it’s contents as H(Node Data) instead within it’s own subsection.

I think having the encoding-related definitions in terminology seems excessive because then reading the TLV section would require fairly long jumps between terminology and TLV section.
