 If a WMS contains extra informations as proposed here (a.k.a. WMS-C):
 http://wiki.osgeo.org/wiki/WMS_Tile_Caching, we can take advantage of them
 by parsing the addition information.

 This has been done in GeoServer/GWC.

 The structure used is described as:

 {{{
 <!ELEMENT VendorSpecificCapabilities (TileSet*) >
 <!ELEMENT TileSet (SRS, BoundingBox?, Resolutions, Width, Height, Format,
 Layers*, Styles*) >
 <!ELEMENT Resolutions (#PCDATA) >
 <!ELEMENT Width (#PCDATA) >
 <!ELEMENT Height (#PCDATA) >
 <!ELEMENT Layers (#PCDATA) >
 <!ELEMENT Styles (#PCDATA) >
 }}}

 An example is:
 {{{
     <VendorSpecificCapabilities>
       <TileSet>
         <SRS>EPSG:900913</SRS>
         <BoundingBox SRS="EPSG:900913" minx="-1.3697515466796875E7"
 miny="5165920.118906248" maxx="-1.361924394984375E7"
 maxy="5244191.635859374"/>
