This at first appears to be a corrigible error that I should fix without reporting, but I fear that there's something I'm missing. So I'm reporting it.
In #CONOIXgen , the Guidelines say:
In the simplest case, a single headword is supplied by an term elements contained by an index element:
<p>The students understand procedures for Arabic lemmatisation <index> <term>Lemmatization, Arabic</term> </index>and are beginning to build parsers.</p>
The effect of this will be to generate an index entry for the term ‘Lemmatization’, referencing the location of the original index element.
Shouldn't that last sentence have ‘Lemmatization, Arabic’ instead of just ‘Lemmatization’?
