I believe the answer is:
ahem
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">your attention please</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for ahem that I've seen before include "Throat clearance to attract attention" , "Excuse me!" , "I say!" , "Gentle utterance to attract attention" , "It's said to gain attention; ah, me (anag.)" .)
