so as not to repeat the grid definition, move it out to its own configuration tags:

<grid name="latlong"> <extent>.....</extent> <resolutions>.....</resolutions> </grid>

<tileset ...> <grid>latlong</grid> ... </tileset>

the configuration will also predefine some default commonly used grids: * latlong for the default grid used for wgs84 latlong in openlayers * google for the default grid used in epsg:900913, along with the resolutions used in googlemaps
