The Web Feature Service (WFS) is able to describe its capabilities. It indicates what feature types (contents) it can service and what operations are supported on each feature type. The service can return what feature types are available based on the feature type alias. The GetCapabilities operation is used to request a capabilities document from the OGC WFS. It issues an XML request to the WFS and gets a response that describes the capabilities of the WFS.
