includes on resource tag not documented as being a list

according to the product documentation at http://maven.apache.org/maven2/maven-model/maven.html each resource should be able to specify includes. maven errors out unless the inclues is moved out of "resource" and into the "resources" tag.

example model:
<resources>
<resource>
<directory>src/main/wsdd</directory>
<includes>*.wsdl</includes>
</resource>
</resources>
