Summary: The document is ready for publication as a standards track RFC

Major issues: none

Minor issues: none

Nits/editorial comments:

- The second sentence of the Abstract reads:

  This specification describes the Minimum Rank Objective Function with
  Hysteresis (MRHOF), ...

But the title (two lines above) reads slightly different:

  The Minimum Rank with Hysteresis Objective Function



I suggest o always use the same term. Since the selected acronym is 


MRHOF, I would suggest to always use the title to refer to MRHOF.







- Section 1, last paragraph. The second sentence in this paragraph is 


incomplete.




- Please expand acronyms at first usage. This includes: DODAG, ETX

- Section 3.1. Towards the end of the section, the sentence reads:

   The path cost corresponding to a neighbor SHOULD be re-computed each
   time:



and then there are 3 conditions numbered from 1 to 3. It is not clear if 


the path cost should be recomputed when all of the 3 conditions are met, 


or when any of the 3 conditions are met. In other words, it is not clear 


if the 3 bullet points are an "AND" or an "OR" operation among then. 


Presumably they are an "OR". If this is the case, perhaps the sentence 


should be rephrased as:




   The path cost corresponding to a neighbor SHOULD be re-computed each
   time any of the following conditions are met:
