Charles, have you been looking at my new EARL[1] stuff, or are we just thinking in parallel? It is indeed possible for a tool to generate its own IDs for every node in a DOM, and use these internally to reference them. An EARL tool can also export them, provided it makes available the IDs themselves (as in my latest tool[1]) and/or machine-readable instructions for reconsructing them as previously discussed ([2], etc). The former simplifies a document snapshot, whereas the latter is still necessary if we want rubustness across document changes.
