Oracle XML Publisher Admin - Modifying a template

We have a check template that I am trying to modify with the following logic

Pseudo logic:    When paymentstatus/code = ‘VOID_BY_OVERFLOW’ print *VOID* else when Addressee is not null print Addressee, otherwise print Name

Current Logic

<?xdofx:if ../PaymentStatus/Code = 'VOID_BY_OVERFLOW' then '****** VOID ******'  else ../Payee/Name end if?>

I have tried the below options but neither work.   Option 1 is close but it does not recognize Addressee having a value.

Option 1

<?xdofx:if../PaymentStatus/Code='VOID_BY_OVERFLOW'then'*VOID*'elseif ../Payee/Address/Addressee=null then ../Payee/Name else ../Payee/Address/Addressee end if?>

Option 2

<xsl:choose>
