| AutoStart | YesNoType | Specifies whether to automatically start the web site. |   | 
| ConfigureIfExists | YesNoType | Specifies whether to configure the web site if it already exists.  Note: This will not affect uninstall behavior.  If the web site exists on uninstall, it will be removed. |   |

| DirProperties | String |                          References the Id attribute for a WebDirProperties element that specifies the security and access properties for this website root directory.

| SiteId | String |                        Optional attribute to directly specify the site id of the WebSite.  Use this to ensure all web                       sites in a web garden get the same site id.  If a number is provided, the site id must be unique                       on all target machines.  If "*" is used, the Description attribute will be hashed to create a unique                       value for the site id. This value must be a positive number or a "*" or a formatted value that resolves                       to "-1" (for the same behavior as "*") or a positive number or blank.  If this attribute is absent then                       the web site will be located using the WebAddress element associated with the web site.                      |   |
