You can do this, but you have to do it backwards -- set the required
attribute when the other field changes. As in:
Married: <input type="checkbox" name="married"
onchange="spouseName.required = checked">
Spouse's name: <input type="text" name="spouseName">
(Although you're more likely to just toggle disabled instead of required,
to be honest.)
You could also do it in the "forward" way like this:
<input type="text" name="spouses_name"
onformchange="required = maritalstatus.value=='married'" />
...where onformchange fires every time the form changes.
