A word or phrase tagged with <foreign> serves to indicate that this text is written in a different language from the main body. It usually appears in italics in final presentations.

It is not necessary to include it in the titles of works mentioned or cited as bibliography.

We need to indicate which other language the text is in:

<p>La palabra <foreign xml:lang="”grc”">ἄνθρωπος</foreign> es muy frecuente…</p>
