<!DOCTYPE family [
<!ELEMENT family (person+, pet*)>
<!ELEMENT person EMPTY>
<!ATTLIST person
name CDATA #REQUIRED

<!ELEMENT pet EMPTY>
<!ATTLIST pet

]>

<family>
<person name="Freddy" / >
<person name="Mary" />
<person name="Jimmy" />
<pet name="Bonzo" type="cat" />
<pet name="Arnie" type="dog" />
