This XSD is correct (semantically and syntactically). I validate also by XMLSpear

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema elementFormDefault="qualified" targetNamespace="http://yourNamespace"
    xmlns="http://yourNamespace" xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <xs:complexType name="ObjectType"/>

    <xs:complexType name="Message">
        <xs:complexContent>
            <xs:extension base="ObjectType">
                <xs:sequence>
                    <xs:element name="element1" type="xs:string" minOccurs="1" maxOccurs="1">
                </xs:element>
                </xs:sequence>
            </xs:extension>
        </xs:complexContent>
    </xs:complexType>
</xs:schema>

Here there are examples of extensions. http://www.w3schools.com/

Solution without extension

<?xml version="1.0" encoding="UTF-8"?>
    <xs:schema elementFormDefault="qualified" targetNamespace="http://yourNamespace"
        xmlns="http://yourNamespace" xmlns:xs="http://www.w3.org/2001/XMLSchema">


        <xs:complexType name="Message">
            <xs:sequence>
                <xs:element name="element1" type="xs:string" minOccurs="1" maxOccurs="1"/>
            </xs:sequence>
        </xs:complexType>
    </xs:schema>
