I have the following comments on this document 1. I find the following statement ambiguous: CCC is not used to constrain MIME encapsulated data, i.e., MIME wrapping layers are not processed with regard to CCC. I do not know if this means that processing is to stop at a MIME encapsulation layer, or if it means that the id-data content type cannot be constrained. (Or perhaps both meanings are correct.) IF the first is meant I would suggest "CCC processing stops when a MIME encapsulation layer is encountered." If the second is meant then it should say "CCC cannot be used to constrain the creation of the id-data content type." 2. It is my personal opinion that the algorithm as described is overly confusing. I was able to fully understand the procedure only by interacting with the authors and not from the document. While there have been some changes to the text since that time, I do not believe that the basic problems with making the algorithm clear have been addressed in the document. I did supply what I considered to be a much simpler version of the algorithm to the authors, but they decided not to make the changes that I outlined in my suggested text.
