My viewer has support for a TOC populated from NCX navMap entries.
However some books I have come across have some pages in the navMap section and some pages only in the pageList section.
e.g.

<navMap>
<navPoint class="h1" id="ch1">
<navLabel>
<text>Title</text>
</navLabel>
<content src="title.html#ch_1"/>
<navPoint class="h2" id="ch_1_1">
<navLabel>
<text>Title</text>
</navLabel>
<content src="title.html#ch_1_1"/>
</navPoint>
</navPoint>
</navMap>

<pageList>
<pageTarget id="p1" type="normal" value="1">
<navLabel><text>1</text></navLabel>
<content src="pages.html#p1"/>
</pageTarget>
<pageTarget id="p2" type="normal" value="2">
<navLabel><text>2</text></navLabel>
<content src="pages.html#p2"/>
</pageTarget>
</pageList>

I could just add pages after the navMap contents but I'm concerned that it's perfectly valid to populate both navigation types from the same source xhtml and I don't want parts of the book effectively appearing twice, once for the navMap and once for the pageList.
e.g.

<navMap>
<navPoint class="h1" id="ch1">
<navLabel>
<text>Chapter 1</text>
</navLabel>
<content src="book.html#ch_1"/>
<navPoint class="h2" id="ch_1_1">
<navLabel>
<text>Chapter 1</text>
</navLabel>
<content src="book.html#ch_1"/>
</navPoint>
</navPoint>
</navMap>

<pageList>
<pageTarget id="p1" type="normal" value="1">
<navLabel><text>1</text></navLabel>
<content src="book.html#p1"/>
</pageTarget>
<pageTarget id="p2" type="normal" value="2">
<navLabel><text>2</text></navLabel>
<content src="book.html#p2"/>
</pageTarget>
</pageList>

The specs seem vague on what to do. What is the recommended way to deal with this situation?
