     As you note, x and z cannot be sensibly be combined with decimal digits to
     create values with some bits known and others unknown. There is not a
     single decimal digit that decides the value of a particular bit in the
     result.
     
     A decimal constant can still use a single x or z digit to indicate that
     the entire number is x or z.
     
     You are right that there doesn't seem to be a description of this in the
     text.
