I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">lorraine's partner</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 alsace that I've seen before include "Region in France, occasionally German" , "source of French wines" , "Region of France famous for white wine" , "Region of France, capital Strasbourg" , "Filled pastry" .)
