Derived data types share many of the same characteristics as the _____ data types they are derived from, but with one or two additional restrictions or modifications.

Case 3-2 Judy has begun to apply the basic information that you have given her about schemas, and she would now like your help in mastering the details of how schemas work.  Judy has included the following element definition in her schema:      <xs:element name="ingredient">             <xs:complexType>                   <xs:sequence>                         <xs:element name="name" type="xs:string" />                         <xs:element name="amount" type="xs:string" />                   </xs:sequence>             </xs:complexType>      </xs:element> -Judy would like to indicate that the ingredient element must appear at least once in a recipe, and that it cannot appear more than 20 times. Which of the following should she add to the element declaration to indicate these restrictions?
