It would be interesting to see what exactly is included (e.g. maps), but maybe more details are only available later in the recognition procedure?
Yes, only when the sites are officially nominated they create a nomination dossier with all the full data (including maps). To submit a Tentative List. only a short form
has to be filled in, and it doesn't seem to be checked for completeness or whether it makes sense. Sometimes the TWHS are mere 'ideas'
