The System.Web.Services.Discovery.DynamicDiscoveryDocument class is employed by the System.Web.Services.Discovery.DiscoveryRequestHandler class's DiscoveryRequestHandler.ProcessRequest(System.Web.HttpContext) method, which handles an HTTP request for a discovery document. The request specifies another document, an XML dynamic discovery document containing a list of directories to exclude. The list corresponds to the System.Web.Services.Discovery.DynamicDiscoveryDocument class's DynamicDiscoveryDocument.ExcludePaths property and contains directories at or below the directory containing the XML document.

Normally, none of these classes need to be used directly by a developer.
