How can I declare that element in DTD allows null values?
I read in one site that we have to use Attributes and use "#IMPLIED" for
Allows NULLS -- Use the ? suffix --- Declare as #IMPLIED
But I want to allow null values for element?
I know that EMPTY element does not allow values. Then what is the purpose of
having EMPTY element in DTD? Can this serve my purpose of allowing null
Thank you for your help
