TEI writing convention for pointing to xml:id values

[JulieGiovacchini]

Hello, I am very interested in using Scholarly xml in class for teaching TEI to DH students. It would be great if we could have a solution to use TEI convention of referencing an ID value with a hashtag (#) in the value's attribute pointing to the ID, like for example: <persName xml:id="DL">Diogenes Laertius</persName><del resp="#DL">blabla</del>

It would be a serious improvment for TEI community !
