So this is the generated code, not your original XForms source, so I'm  
guessing here, but to set a value to the empty string, you use either

   <setvalue ref="foo" value="''"/>

or equally good

   <setvalue ref="foo"/>

This is not good:

   <setvalue ref="foo" value=""/>

because @value has to be an expression.
