I have reviewed this document and I would say that this is a well thought-out and structured document. I have marked it as ready with nits based on the following:

* 3.  MACAddress otherName:  "object identifier (OID)", the 'O' and 'I' should be capitalised. 

* 3.4.2.  OtherName.MACAddress Path Validation Processing: "permitted_subtress" should be "permitted_subtrees" (typo)
