Using parent POMs effectively

I've created a parent POM, in which to house a few common dependencies,
but mostly to set up how a site is built:

        *  CheckStyle rules,
        *  JavaDoc stylesheet,
        *  JXR stylesheet,
        *  site stylesheet.

But the latter site.css is not being picked up:  It lives in
src/site/resources/css/site.css
under the parent project.  If I put site.css under the child project, it
is copied to
target/site/css just fine.

Should I be able to put such resources under the parent POM's project?
I've even tried specifying the following in the parent POM:

    <reporting>
        <plugins>
           <!-- Site -->
           <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-site-plugin</artifactId>
                <configuration>
                    <stylesheet>
 ${env.FSB_PROJECTS_HOME}/fsb-master-pom/src/site/resources/css/site.css
                </stylesheet>
                </configuration>
           </plugin>
          ...

It'd be nice to specify such things once in the parent project to be used
by all child projects.

Ideas?
