There are many arbitrary choices when designing a data structure to
represent text.

You'd regret that quickly: what do you do for inline markup (e.g.
bold, italics)? You'd have to introduce a special markup for
"normal" text. Good-bye "lightweight markup" :)

This is XML's "mixed content". Note that specific XMLs can and
do limit that, via DTDs or other validation restrictions (aka
schema). If you're doing text using some suitable XML schema,
you most probably won't be able to put a whole paragraph whithin
a section title. Or a table. If you want a whole italics stretch
straddling a paragraph boundary, you'll have to close it before
the paragraph's end and re-open it next paragraph or something
(although they might, logically or philosophically, belong
together).

Human language is too exciting to fit into a tree structure.

You'll always end up offending some hierarchy some of the time.
In some places you can be sent to jail for that ;-)

No, seriously: Document models sometimes get stretched to data
description languages (I always cringe when people talk about
a JSON or YAML "document") and vice-versa. This is a strength,
but also a weakness.

And don't forget, OASIS's OpenDocument format also doesn't seem
to support "going back". Perhaps for a reason.
