Attributes and Elements

The following sections describe the attributes, child elements, and parent elements.

Attributes

Attribute	Description
description	Required String attribute. Describes the site map provider.
name	Required String attribute. Specifies the name of the provider to add.
siteMapFile	Optional String attribute. Specifies the file that contains the site map data. The siteMapFile reference can be any one of the following: A path reference that is relative to the application (for example, `~/SiteMapFile1.sitemap`). A virtual path that maps to a location that is within the directory structure for the application (for example, `/directory1/directory2/SiteMapFile1.sitemap`). A path reference that is relative to the root of the directory structure for the application (for example, `SiteMapFile1.sitemap`).
type	Required String attribute. Specifies a type that implements the ProviderBase class. The type value must be a fully qualified assembly reference.
securityTrimmingEnabled	Defaults to false. If true, and if the provider includes the necessary logic, the site map provider performs a role check against retrieved nodes. The provider also performs a role check against the current user. The URL authorization rules for the application are applied and if Microsoft Windows authentication is being used, the file authorization rules for the application also apply.

Child Elements

None.

Parent Elements

Element	Description
configuration	Provides the root element in every configuration file that is used by the common language runtime and the .NET Framework applications.
system.web	Specifies the root element for the ASP.NET configuration section.
siteMap	Defines configuration settings to support the navigation infrastructure for configuring, storing, and rendering site navigation.
