I don't think I'm understanding you here. Which embedded structure are
you saying raw text contains? Do you mean punctuation, paragraph
If I'm understanding zigzag correctly, if you think of a collection of
text in zigzag, the letters are cells, one dimension creates words,
another creates sentences, another creates paragraphs, etc. In that
sense dimensions represent structure and cells represent content. I
guess ents and enfilades do the same sort of thing.
I do think that Nelson is on to something when he suggests that
structure must be a layer above the content. It's very hard, though,
to express exactly why.
