I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">egyptian dam</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for aswan that I've seen before include "Site of dam on the Nile" , "Large dam in Egypt" , "Ancient city on the Nile" , "Egyptian city and dam" , "Egyptian town and dam" .)
