<geography>

The <geography> tag specifies the area covered by a map. As such, it is only used as a child of a <map>.

The geography attribute was the original mechanism for defining the area of a map. The <geography> was introduced in a subsequent version of WxML to provide more flexibility when defining map areas. When both are specified, the <geography> tag takes precedence over the geography attribute. Although both methods are currently supported in WxML for convenience, it is likely that one or both of them could be obsoleted in future versions in support of an improved mechanism.
