I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">a b c d e f or g</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 note that I've seen before include "Tone of importance" , "Quaver, say" , "Observe; paper money" , "Comment" , "Heed; short letter" .)
