I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">enigma variations composer</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 elgar that I've seen before include "Nimrod composer" , "[NIMROD] 's creator" , "He scored" , "Out of the strange glare comes an English composer" , "Scorer" .)
