Language sensitive citation based on document language
The German DGP style recommends the usage of English terminology for the citation and referencing of English texts (cf. 14.12 Fremdsprachige Publikationen zit. in Deutsche Gesellschaft für Psychologie, 2007, S. 91-92).
Full reference:
Deutsche Gesellschaft für Psychologie. (2007). Richtlinien zur Manuskriptgestaltung (3. Auflage). Göttingen: Hogrefe.
For example:
Abkürzungen Englischsprachiger Werke
ed. (edition); 2nd ed. (second edition); Ed. (Editor); Eds. (Editors), p. (Page), pp. (pages), Vol. (Volume); Vols. (Volumes).
Would it be possible to substitute the APA field descriptors within the DGP style when the language field in the entry is set to English?

But to give you a sense, here is a multilingual style that I customized for someone a year ago:

essentially you need multiple layout elements for both the citation and the (in this case non-existent) bibliography section.
<choose>
<if is-numeric="edition" locale="ja zh kr" match="all">
<group>
<text value="第"/>
<number variable="edition"/>
<text value="版"/>
</group>
</if>
<else-if is-numeric="edition">
<group delimiter=" ">
<number variable="edition" form="ordinal"/>
<text term="edition" form="short"/>
</group>
</else-if>
<else>
<number variable="edition" text-case="capitalize-first" suffix="."/>
</else>
</choose>
