Then modify the structure map for the issue (found further below in the mets xml file). Revising the structure map will allow you to designate where the section label occurs in the hierarchy of the issue, as well as pinpoint which particular pages are part of that section. Example:
<structMap xmlns:np="urn:library-of-congress:ndnp:mets:newspaper">
<div TYPE="np:issue" DMDID="issueModsBib">
<div TYPE="np:page" DMDID="pageModsBib1">
<fptr FILEID="masterFile1" />
<fptr FILEID="serviceFile1" />
<fptr FILEID="otherDerivativeFile1" />
<fptr FILEID="ocrFile1" />
</div>
<div TYPE="np:page" DMDID="pageModsBib2">
<fptr FILEID="masterFile2" />
<fptr FILEID="serviceFile2" />
<fptr FILEID="otherDerivativeFile2" />
<fptr FILEID="ocrFile2" />
</div>
<div TYPE="np:page" DMDID="pageModsBib3">
<fptr FILEID="masterFile3" />
<fptr FILEID="serviceFile3" />
<fptr FILEID="otherDerivativeFile3" />
<fptr FILEID="ocrFile3" />
</div>
<div TYPE="np:page" DMDID="pageModsBib4">
<fptr FILEID="masterFile4" />
<fptr FILEID="serviceFile4" />

<div TYPE="np:page" DMDID="pageModsBib8">

</structMap>
The first four pages are part of the traditional newspaper issue and the last four pages are part of a new section label. You will notice that after pageModsBib4 there is an opening tag for the sectionModsBib1 section label. If you scroll down you will also notice that the section label closes after pageModsBib8, which associates pages 5, 6, 7, and 8 with the section label.
