I’ve seen in the mysqli documentation two referentes &reftitle.returnvalues and &reftitle.seealso, but not in all functions
And I think that It would be good if it is defined to be used rather than the <title></title> way. And as a translator it is nice to
Skip this template statements, and if it is extended to more titles like <title>Description<title> and so on… It would be really nice for translators like me J, but it depends on the agreement between the doc writers. So I leave this comment to be consider to whom it may concern.
I am fine with using entities. IMHO it is just a matter of someone replacing the titles.
