Did you try:
     //*[@Mandatory='True' and .='']
(all the elements which have mandatory='True' and contain no text)
?

Assuming that *all* instances of LastName are mandatory, or at least
all within some specific context, then this information doesn't belong
in the document: maybe you should use a DTD or a schema.  If you want
to stick to just using XSLT, then schematron might be worth a look.
