DTD:

<!ELEMENT ElementName (enum1 | enum2 | enum3 | enum4)>

XML Schema:

<xs:element name="ElementName" type="Enum"/>

<xs:complexType name="Enum">
 <xs:choice>
  <xs:element name="enum1" type="xs:string"/>
  <xs:element name="enum2" type="xs:string"/>
  <xs:element name="enum3" type="xs:string"/>
  <xs:element name="enum4" type="xs:string"/>
 </xs:choice>
</xs:complexType>

Or:

<xs:element name="ElementName">
 <xs:complexType>
  <xs:choice>
   <xs:element name="enum1" type="xs:string"/>
   <xs:element name="enum2" type="xs:string"/>
   <xs:element name="enum3" type="xs:string"/>
   <xs:element name="enum4" type="xs:string"/>
  </xs:choice>
 </xs:complexType>
</xs:element>

Or do you want string content of ElementName to be an enumeration?

<xs:simpleType name="Enum">
 <xs:restriction base="xs:string">
  <xs:enumeration value="enum1-string"/>
  <xs:enumeration value="enum2-string"/>
  <xs:enumeration value="enum3-string"/>
  <xs:enumeration value="enum4-string"/>
 </xs:restriction>
</xs:simpleType>

RELAX NG:

<element name="ElementName">
 <choice>
  <element name="enum1"><text/></element>
  <element name="enum2"><text/></element>
  <element name="enum3"><text/></element>
  <element name="enum4"><text/></element>
 </choice>
</element>

Or:

<element name="ElementName">
 <choice>
  <value>enum1-string</value>
  <value>enum2-string</value>
  <value>enum3-string</value>
  <value>enum4-string</value>
 </choice>
</element>

Hi,
  In DTD, i have something like this,
   <Element ElementName   (enum1|enum2|enum3|......)>
   This indicates that ElementName must have atleat one of these
nodes(enum1,enum2,enum3,......).

  How this can be done in XML Schema?.

Regards,
Raja
