Anchors <anchor/> are tags without a content node that can be inserted anywhere in the text to identify that particular location unambiguously. This allows for multiple cross-references and non-hierarchical nestings that we will need in our editions.

It is essential always to use a unique @xml:id that identifies each <anchor/>. The @xml:id that we give it should clearly identify the point where that <anchor> is, by means of the language prefix and the corresponding canonical numbering (book, verse, chapter, subchapter, etc.).

For example, <anchor xml:id="la.1.44"/> means «anchor in the Latin version, in book 1 and verse 44». In this way it will be differentiated from any other anchor at the same point but in the translations, which will be <anchor xml:id="es.1.44"/> or <anchor xml:id="en.1.44"/>.

But, following the example, it could also be that several anchors appear within the same verse, so each one will need to have a different @xml:id . It is always best to number them consecutively at the end of the initial reference, with a system that is easy to remember and can be reproduced well in all translations. For example: <anchor xml:id="la.1.44.a"/>, <anchor xml:id="la.1.44.b"/>, <anchor xml:id="la.1.44.c"/>, and so on.

Care must always be taken to ensure that the @xml:id of an <anchor/> does not match the @xml:id of the tags containing it. The suffix "an" may be used in such cases:

<div xml:id="la.1.44">
	<l n="44>Contenidos del verso <anchor xml:id="la.an.1.44"> que contiene un anclaje</l>
</div>
