Hi Folks,

As you know, a restaurant that offers a buffet style of dining lays out all foods on tables and then customers select the items they want. With a set menu style of dining the customer makes a choice and that determines all the items the customer will receive.

Should an XML Schema be written like a buffet: create a long list of optional elements and then let the instance document author select whichever ones he desires?

Or should an XML Schema be written like a set menu: there is a choice and once the instance document author selects a choice, that determines all the elements for that choice?
