alt element can contain only inline elements. So if you need to use
longer text descriptions, ie. several paragraphs, then you must use
textobject.

This depends on table model used. In DocBook you can use HTML markup or
so called CALS markup for tables. In HTML table you must use summary
attribute, in CALS you can use alt/textobject.

Probably sounds more complex then it should be, but there is long
evolution behind this :-)
