My apologies if this isn't quite the proper forum for this enquiry. This concerns the best and commonly-used practices in relation to the encoding of documents using the TEI-P5.
We have a case within a project being undertaken at the Lafayette College Libraries in which one finds <note place="foot"> elements within line (<l>) elements for a given Document. Further, for the purposes of stemmatic analysis (by means of collation), it would be optimal to link these <note> elements to their parent <l> elements (beyond simply relying upon the structure of the Document tree).
While the TEI (as well as the XML itself) provides a number of approaches through which one could forge these links, I would be very grateful to learn of any common or preferred approaches to implementing similar solutions.
