Check out: http://egeveke.blogspot.com/2006/09/xpathnavigator-missing-setattribute.html

Basically you use MoveToAttribute, testing if it was successful. If not, then it does not exist and you can create. Remember to either start with a clone of you navigator, or move back to the parent when you are successful.

if (nav.MoveToAttribute())
{
  // exists
  nav.MoveToParent();
} 
else
{
  nav.CreateAttribute(...);
}

Use "HasAttributes" property on the Xpathnavigator object to check whether it has any attributes and then continue to do your operation. Hope this helps!!
