Can't use jaxb bindings on individual xsd elements

Question

I'm using jaxb to generate java source code from an xsd file.

I want to be able to specify which packages the sources are generated in on a per element basis, however whenever I generate sources I get the following error:

[ERROR] ****/src/main/xjb/common.xjb[8,24]
com.sun.istack.SAXParseException2: compiler was unable to honor this schemaBinding customization. It is attached to a wrong place, or its inconsistent with other bindings.

My bindings file common.xjb is attempting to place the element with the name (attribute value) 'api' in the package 'com.myxml.common.api':

<jxb:bindings version="1.0" xmlns:jxb="http://java.sun.com/xml/ns/jaxb" xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <jxb:bindings schemaLocation="../xsd/common/common.xsd" node="/xs:schema">

        <jxb:bindings node="//xs:element[@name='api']">
            <jxb:schemaBindings>
                <jxb:package name="com.myxml.common.api" />
            </jxb:schemaBindings>
        </jxb:bindings>

    </jxb:bindings>

</jxb:bindings>

My xsd file common.xsd is:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" version="1.1" xml:lang="en">

    <xs:element name='api'>
        <xs:complexType>
            <xs:simpleContent>
                <xs:extension base="xs:string" />
            </xs:simpleContent>
        </xs:complexType>
    </xs:element>

</xs:schema>

And I'm using the following Maven plugin to get everything going:

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>jaxb2-maven-plugin</artifactId>
    <version>1.5</version>

    <executions>
        <execution>
            <id>schema00-generate</id>
            <phase>generate-sources</phase>
            <goals>
                <goal>xjc</goal>
            </goals>
            <configuration>
                <schemaFiles>common/common.xsd</schemaFiles>
                <bindingFiles>common.xjb</bindingFiles>
                <bindingDirectory>${project.basedir}/src/main/xjb</bindingDirectory>
            </configuration>
        </execution>
    </executions>
</plugin>

Why am I getting this error and how can I resolve it? I don't have any other bindings in use at this stage that I'm aware of.

Elements from the same namespace cannot be mapped to different packages so the package cannot be defined for anything other than the top level
