FormEncode has support for this but I've never been able to figure it
out exactly. You'd put all the fields on one form, and name them
something like 'session-1.description;. The NestedVariables
pre-validator will unpack them into a list of dicts, so you'd use
something like ForEach('session'), with a schema validator for the
session. But I've never quite figured it out so you'll have to read
the FormEncode manual and the source. You can either put a fixed
number of rows on the form, or have a Javascript button to add a row.
