myBatis xml map causing namespace must be declared for element type mapper

Is there anything obvious wrong with this setup please. On app startup I get Attribute "namespace" must be declared for element type "mapper", when it clearly is declared.

spring xml resource dao.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://ift.tt/GArMu6"
xmlns:xsi="http://ift.tt/ra1lAU"
xmlns:util="http://ift.tt/OGfeTW"
xmlns:jms="http://ift.tt/1iMF6wC"
xsi:schemaLocation="http://ift.tt/GArMu6
                    http://ift.tt/18sW2ax
                    http://ift.tt/OGfeTW
                    http://ift.tt/1aj0W5e
                    http://ift.tt/1iMF6wC http://ift.tt/1BuJ5p4">

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="java:comp/env/JNDINAME"/>
    <property name="lookupOnStartup" value="true"/>
    <property name="cache" value="true"/>
    <property name="proxyInterface" value="javax.sql.DataSource"/>      
</bean> 

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
</bean>

<bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer"> 
    <property name="basePackage" value="com.mycompany.dao"/> 
    <property name="sqlSessionFactory" ref="sqlSessionFactory"/> 
</bean>
</beans>

Interface:

public interface MyDAO {    
    public void save(@Param("id") String id);
}

Mapper xml:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
    PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
    "http://ift.tt/1hHoXcX">

<configuration>

<mapper namespace="com.mycompany.dao">

<typeAlias alias="xxxVO" type="com.xxx" />

<insert id="save" parameterType="string">
    SOME SQL etc
</insert>

</mapper>

</configuration>

The Interface is in src/main/java/com/mycompany/dao The mapper xml in in src/main/resources/com/mycompany/dao

My pom has

    <dependency>
        <groupId>org.mybatis</groupId>
        <artifactId>mybatis-spring</artifactId>
        <version>1.2.2</version>
    </dependency>
    <dependency> 
        <groupId>org.mybatis</groupId> 
        <artifactId>mybatis</artifactId> 
        <version>3.2.2</version> 
    </dependency>

Thanks in advance
