No, the manual is. My bad, sort of; I meant to fix it a week ago but
never got around to it.

With the new exporter, the syntax is:

@@odt:<text:span text:style-name="Highlight">@@This is a highlighted
text@@odt:</text:span>@@.  But this is a regular text.

The raw ODT is now wrapped in double @@'s, not preceded by a single @,
and you need to specify the backend after the leading @@'s.

You can do cross-references with ordinary links. Have a look at the
manual section 4.2, "Internal links". However, what you get out of the
box is textual references to e.g. section headings, not page
references. You can change that for each reference individually by
right-clicking on them in LibreOffice. There should be a way to get page
references by default, but off the cuff, I'm not sure how.

Yours,
