Add the remarks section from ENR5.1 for restricted and danger areas to the What's Here section. 

I don't think it's technically feasible to open a PDF with a search active, and unfortunately there's little standardisation in ENR 5.1 documents as to how the area identifiers are formatted so it wouldn't work a lot of the time anyway. If it were doable, that's exactly the sort of thing we'd probably have done already, as it would help us with our data creation too.
