<xs:documentation> This is the XML schema module for the token elements of the content part of MathML. Author: Stéphane Dalmas, INRIA. </xs:documentation>
</xs:annotation>
<!– common content for the token elements –>
<xs:group name=“Content-token.content”>
<xs:sequence> <xs:group ref="Presentation-expr.class"/> </xs:sequence>
</xs:group>
<!– “cn” –>
<xs:attributeGroup name=“cn.attlist”>
<xs:attribute name="base"> <xs:simpleType> <xs:restriction base="xs:positiveInteger"> <xs:minInclusive value="2"/> <xs:maxInclusive value="36"/> </xs:restriction> </xs:simpleType> </xs:attribute> <xs:attribute name="type"> <xs:simpleType> <xs:restriction base="xs:NMTOKEN"> <xs:enumeration value="e-notation"/> <xs:enumeration value="integer"/> <xs:enumeration value="rational"/> <xs:enumeration value="real"/> <xs:enumeration value="complex-cartesian"/> <xs:enumeration value="complex-polar"/> <xs:enumeration value="constant"/> </xs:restriction> </xs:simpleType> </xs:attribute> <xs:attributeGroup ref="Definition.attrib"/> <xs:attributeGroup ref="Common.attrib"/>
</xs:attributeGroup>
<!– the content of “cn” may have <sep> elements in it –>
<xs:complexType name=“sep.type”> </xs:complexType>
<xs:element name=“sep” type=“sep.type”/>
<xs:group name=“cn.content”>
<xs:choice> <xs:group ref="Presentation-expr.class"/> <xs:element ref="sep"/> </xs:choice>
</xs:group>
<xs:complexType name=“cn.type” mixed=“true”>
<xs:group ref="cn.content" minOccurs="0" maxOccurs="unbounded"/> <xs:attributeGroup ref="cn.attlist"/>
</xs:complexType>
<xs:element name=“cn” type=“cn.type”/>
<!– “ci” –>
<xs:attributeGroup name=“ci.attlist”>
<xs:attribute name="type" type="xs:string"/> <xs:attributeGroup ref="Definition.attrib"/> <xs:attributeGroup ref="Common.attrib"/>
</xs:attributeGroup>
<xs:complexType name=“ci.type” mixed=“true”>
<xs:group ref="Content-token.content" minOccurs="0"/> <xs:attributeGroup ref="ci.attlist"/>
</xs:complexType>
<xs:element name=“ci” type=“ci.type”/>
<!– “csymbol” –>

<xs:group ref="Content-token.content" minOccurs="0"/> <xs:attributeGroup ref="csymbol.attlist"/>
</xs:complexType>
<xs:element name=“csymbol” type=“csymbol.type”/>
<!– And the group of everything –>
<xs:group name=“Content-tokens.class”>
<xs:choice> <xs:element ref="cn"/> <xs:element ref="ci"/> <xs:element ref="csymbol"/> </xs:choice>
</xs:group>
