Case 3-1
Judy wants to be able to validate the XML documents that she uses for recipes. These documents include numeric elements that specify ingredient amounts and cooking times, so you recommend that she use a schema instead of a DTD, and you teach her some of the key facts about schemas.
-Judy has an attribute called "recipeType" that she uses to record whether the recipe is for an appetizer, entree, dessert, or other type of dish. This attribute only contains text. Which of the following would be a valid XML Schema definition for this attribute?

Option A is not valid because it does not have the "name" attribute, which is required for attributes in XML Schema. Option C and D are not valid because "PCDATA" is not a valid data type in XML Schema. Option B is the correct choice because it includes the required "name" attribute and uses the valid "xs:string" data type for the "recipeType" attribute.
