Default values

Hi,
 
I know that we can have one dafault specified for any element in the XML
file using DTD or XML-schema. But can we specify a set of default values to
one element.So that when I open a an XML file in browser and that element is
specified empty in the XML file. But there are set of default values
specifed in DTD or XML -schemas, then those set of values should be
displayed...
 
My Question is can we give a set of default values?
 
Bye
