2.6.1 Styling information
The examples below show the styling portion of the GetCapabilities response. The first two come from MapServer services, and show that the legend will be generated on-the-fly using an SLD GetLegendGraphic request. The third example shows a simple request to a static image, generated in advance by the map service provider.
