I'll try to provide what assistance I can.
The wording in this proposed clause, other than new paragraph 1.1(c), is fairly close to what appears in section 25 of the charter. In that sense there is a precedent for it, admittedly in a very different context.
Without getting into what is included in new paragraphs 1.1(a), (b), and (c) and whether something is missed, I would simply point out that the opening part of that provision talks about aboriginal treaty rights and other rights and freedoms, including what's listed in those new paragraphs. So in that sense, I suppose--this hasn't been interpreted by the courts very much--that new paragraphs 1.1(a), (b), and (c) in one sense may well be examples of what is in the umbrella clause of the opening words of clause 1.
I'm just not sure it's necessary to get into what's in new paragraphs (a), (b), and (c).
