In this (pre-xml) reference, Nelson advocates having the equivalent of
markup contained in a separate document rather than inline with the main
document. He says that this would constrain the structure of the base
document less than inline markup would. It's interesting that the
Multivalent approach does just that for annotations and notes:

Of course, you still have to connect parts of the overlay to their
corresponding parts in the base document, which Nelson imagines you would
do by counting bytes - the Multivalent approach uses its own document model
combined with what they call "Robust Locations" to accomplish this.
