What you want is
widget=IntegerWidget(label="Number of Years Married",
condition="object/isMarried")
however this will not cause the widget to appear and disappear dynamically.
That would require javascript. Another option to assign your IntegerField to
another schemata, then it will by on a later edit page, and will only appear
if the condition is met. If you want the fields on the same page and you
want the visibility of one to depend on the value entered in another, then
look at MasterSelectWidget (
http://plone.org/products/masterselectwidget)
which was designed for this purpose among other things.
