An excellent set of test cases!

By default, images "float" -- so on page 7 (Figure 1) it "floats"
to the top of the current page. This may not be the best default
behaviour -- I'll see if we can improve it.

Yes, if we have low resolution and high resolution versions, we
want to use the low resolution version on the web and the high
resolution version in print. We achieve that like this:

[[http://link.to.hi.res.image | http://link.to.lo.res.image]]

On the web page, this displays the lo res image as a link to the
hi res image. In print, it will use the high res image. This also
gives authors a way to have different size images for print and web.

At the moment, the print dtd doesn't have an equivalent tag.
I'll have to investigate what we might do. The general
approach is that an administrator writes:

if ($format=='pdf')
    Markup('xyz','position','match expression','print substitution');
else
    Markup('xyz','position','match expression','html substitution');
