In fact, there is no concept of inheritance between areas: it's my
fantasy. But we have postulated a thing of the kind for footnotes -
in our implementation, footnotes can inherit properties from the
embracing area-container (fo:static-contents or fo:flow). I have found
no other solution to set common font traits for all footnotes. To
describe such a disrupted inheritance, it is straightforward to
reformulate it in terms of inheritance of traits between areas
generated by objects, rather than inheritance of properties between
objects themselves.

My idea was to extend the same approach to table-columns;
but it is not backed by the spec.

No. I mean it is legal because XSL FO are deliberately unvalidatable ;-(,
but should not produce any effect.

(I wonder if this is more acceptable than just writing  text-align="start".)
Anyhow, we should specify this value explicitly on _every_ cell,
and process it there; no per-column defaults.

Here again, like in lists, the spec wants me to write lengthy expressions
instead of letting me set reasonable defaults. This is its current style.
