It's a widget for sequence types, such as lists and tuples. Imagine the
following schema were represented as an HTML form:

from zope.interface import Interface
from zope.schema import List, TextLine

class IFoo(Interface):

  alist = List(value_type=TextLine())

SequenceWidget will take care of rendering the widget for the 'alist'
property.

It's all explained in my book :)
