Summary on the Use of @ref and @corresp

The TEI Guidelines provide the following clarification on @corresp Essentially, what the corresp attribute does is to specify that elements bearing this attribute and those to which the attribute points are doubly linked. ... the correspondence relationship is not ‘from’ one to the other, but ‘between’ the two objects.

For internal references you can use

1. <ref type="quire" corresp="#q12">↗
2. <ref target="#q12 #q13">↗
3. @corresp with a value starting with # (the ID anchor) points always to a @xml:id WITHIN THE DOCUMENT

If @corresp is used to point to an element inside another document with an ID, as for witness and div in a work record, then it does not need an initial # like in this example from LIT1560Gospel

<div type="textpart" subtype="chapter" xml:lang="gez" xml:id="IntroductionEpistle" corresp="LIT1349EpistlEusebius">
<label>Epistle to Carpianus by Eusebius</label>
</div>
        

• If you point to an internal anchor in a @xml:id inside the document you are working with, use # to begin with and your editor should prompt for you a list of available IDs.

• If you point to an external ID don't start with #, just enter the ID. That is why <witness>↗ does not take that, as @active, @passive inside <relation>↗ should not. You want to be able to point to anchors within the records you are pointing to and link things like LIT1560Gospel#t2.
