Thanks... that's helpful... What I'm working with is a mix of XHTML, DAISY, Dublin Core and IDPF documents. They are in directory structures that may live online at different locations, or may be downloaded as a single archive (ZIP). In any case, the locator needs to point to the same fragments and ranges unambiguously. It also needs to identify the package itself, independently of any other URL, so correlation can be mad between various online versions and downloaded copies. In the online form, my locator has to be part of another locator, ie a URL fragment (it's used in an ajax application). I was thinking I should use Xpath on a cross-document basis, as a top down path through the whole package, but maybe it makes more sense to reference the content documents themselves.
