As we are no longer using a box model, then it is likely someone might
want to describe how to separate properties, making this change
unworkable (i.e., it will not be clear which content is being separated,
values or properties). As much as I don't like format description
because of the difficulty it introduces in writing the ontology, it does
seem like an important element.

On a separate issue, is contentLast taking the place of the last comma
produced by contentAfter? Or is it going to look like:

  'red, green, orange, .'

Could we say contentBetween in addition?
