What contexts can document instances have? The link is the actual multi-ended relationship. The link description is the result of processing the link description element. It has all the information needed to build a link, but I call it a mapping because the SAME link description can result in DIFFERENT links depending on where it sits in its host document, and where that document sits itself, because of relative elements in the locators used to identify the endpoints. Your question also gets us into the metadocument thread, because the most obvious aspect of context which affects what link instantiates a link description in any particular case is the catalog, supposing the one of its locators uses an FPI. Does this clarify? ht
