4) We modify the Default XE XAR to have titles for all
its pages (and
remove the header 1 in page content)
This should also mean changing all =headings=
to ==headings==, since
semantically speaking, now that the page title is displayed with h1,
everything
under should be a h2, in a "normal" semantic.
Details for 4):
- add titles
- remove h1 since they're not needed anymore
- move existing h2 to h1
