Thomas,
Setting <wgs84bbox> ... </wgs84bbox> had no impact. I wasn’t sure if the
format was space delimited or comma delimited so I tried both ways. I assume
that is the correct order is minX, minY, maxX, maxY.
Here is what I tried:
<tileset name="LyonAirPhotos">
<source>LyonAirPhotosSource</source>
<cache>disk</cache>
<metadata>
<title>Lyon CACHE</title>
<abstract>blabla</abstract>
<wgs84bbox>-96.1 44.1 -95.58 44.7</wgs84bbox>
</metadata>
<grid>LyonCC</grid>
<format>myjpeg</format>
<metatile>5 5</metatile>
<metabuffer>10</metabuffer>
<expires>3600</expires>
</tileset>

you can try setting
<metadata>
<wgs84bbox> ... </wgs84bbox>
</metadata>
in each of your <tileset>s, this should populate the LatLonBbox in the
capabilities.
