These rights should include: (1) The right to be conceived with a natural biological heritage -- that is, to have unmodified biological origins -- in particular, to be conceived from a natural sperm from one identified man and a natural ovum from one identified woman; and (2) the right to know the identity of one's biological parents.
This is better language than the PCBE's proposal (which this site is dedicated to enacting) because she adds the words "unmodified", "natural", "identifiable", and "man" and "woman". I agree that the law must add those important words, or else someone will try to call a sperm an egg or something (in spite of the proper defintion of sperm as being a "male gamete", ie, the gamete of a male).
And she is doing a great job of selling it by tying it in with donor conception, and referring to the growing chorus of donor conceived adults who want to save other people from being conceived the way they were. I wouldn't have thought to consider these issues together, but by putting them under the same heading of "children's rights", she comes up with a great new approach.
I disagree with her choice to imply that same-sex marriage can coexist with her first right, as it would create, for the first time in history, marriages that, by law, cannot procreate. Usually, we don't give marriage licenses to couples that are prohibited from procreating together, and I think it is a terrible mistake to start now. I assume she does that so that "children's rights" don't get caught up in the SSM debate, and it's true they are important on their own. But I think it works better to link them together.
