I think it could be either:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">milk source</span>' is the definition.<br/ ><span class="explanation-format__explanation">(building which processes cow's milk)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for dairy that I've seen before include "Milk processing plant" , "Type of farm" , "Place for storing milk products" , "Business supplying milk etc" , "Creamery" .)
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">milk source</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 udder that I've seen before include "Teat of a cow" , "Natural container for milk?" , "Mammary gland of cows, sheep etc" , "What's at rear on cows" , "Animal mammary gland" .)
