Help with element with just one attribute

Recommended Posts

Hello,I need a XSD schema to validate an XML. It has to define just one element (and the root) call "EL_ONE" which has no elements and its text can be a number between 0 and 7. The lement must have an attribute call 'Id' (a string).I have this schema but it's not correct:

<xs:schema > <xs:element name="ELEMENTS">	<xs:complexType> 		  <xs:sequence>				  <xs:element ref="EL_ONE" />				  </xs:sequence>					</xs:complexType></xs:element>	 <xs:element name="EL_ONE"" type="ZERO_SEVEN_Type"/>		<xs:complexType name="ZERO_ONE_Type">  <xs:simpleContent>	<xs:extension  base="xs:integer">	<xs:attribute name="id" type="xs:string" />   <xs:restriction base="xs:integer">		  <xs:minInclusive value="0"/>		  <xs:maxInclusive value="1"/>   </xs:restriction>   </xs:extension > </xs:simpleContent></xs:complexType> 	</xs:schema>
