This particular WHS is designated to be of outstanding universal value: UNESCO used a similar, perhaps identical, wording. However, the phrase 'outstanding value' doesn't quantify how much value it has, just that it is outstanding. I agree that it is outstanding.

My personal opinion is that it will be possible to quantify that value at some point in the future. However, I doubt that quantification will occur in a timescale that will affect the outcome of this consultation. Nevertheless, I'll look into the possibility of putting in a holding set of arguments in the current consultation. If you're contributing to the consultation, I wish you luck Nigel.
