Copyright statement not building

问题

For me, this builds the preface content, but no copyright matter. The file location is correct.

From my ditamap:

<frontmatter>
 <notices format="dita" href="preface/src/c_copyright.xml" linking="none" navtitle="Copyright and disclaimer" scope="local" toc="no" type="concept">
 </notices>
 <booklists>
    <toc/>
 </booklists>
 <preface navtitle="nested Preface inside">
    <topicref format="ditamap" href="maps/GSGettingStarted_preface.ditamap" navtitle="GSGettingStarted_preface">
    </topicref>
 </preface>

Am I using the notices element incorrectly?

Thanks
