Indeed, it is hard to imagine a BibTeX file devoid of such markup.
How would one indicate the (reverse) emphasis of a quoted book title,
as in /The Cambridge Companion to /Ulysses, except by indicating the
emphasis of "Ulysses" and letting ConTeXt reverse it when emphasizing
the complete title? (§4.21 of the APA2013 spec requires this.)
title={The Cambridge Companion to {\em Ulysses}},

I would think that the proper form would be

title={The Cambridge Companion to {\it Ulysses}}

since \em could be, and is by default, slanted, but the standard here calls for italic.

1. How many fonts provides a italic *and* slanted style.

2. You change for the style for \em.

That brings up the question of when one should use \em, \emph, and \emphasized, all of which appear in font-emp.mkvi. The wiki and other documentation provides no guidance.

\starttext

normal {\em emphasized}

{\it normal {\em emphasized}}

\stoptext

It does not matter how many fonts support both (LM does, and Libertine). One feature of a BibTeX file is reusability for many documents, and when the file is created you do not know what will be the default emphasis of the document. By explicitly coding \it, you are assured that the italic face will be attempted. If it is not available, there should be an error message, and you can then have a discussion with your editor. The claim of the new bibliography subsystem is that it will implement APA strictly, and that calls for italic.

I understand as well that \em allows switching (reverse emphasis as noted above). It also provides some italic correction. I am asking about the appropriate use of the two variations of \em: \emph  (which is a grouped command \em) and \emphasized (defined as \bgroup\em\let\nexttoken). I understand and make use of grouped commands -- they are largely syntactic sugar, but I like sugar. I am less certain of the purpose of \emphasized, how it works, and why it might be useful. I do not recall seeing a command definition with a bgroup and no egroup before.
