SYMPTOMS

Consider the following scenario:
  • You have Internet Information Services (IIS) 7.0 installed on a server.
  • You define a non-collection element in the configuration schema file.
  • However, you do not define any child elements for this element, and you do not define any attributes for this element.
In this scenario, the Microsoft.Web.Administration (MWA) API cannot determine whether the element is present or not in a given IIS configuration file.

For example, you define the system.webServer/example section schema in the configuration schema file as follows:
<sectionSchema name="system.webServer/example">
<element name="e" />
</sectionSchema>
In this example, the element e is a non-collection element. Additionally, the element e has no child elements and has no attributes.

Now consider the following two configuration examples:

Configuration 1
<system.webServer/example>
<e />
<system.webServer/example/>
Configuration 2
<system.webServer/example />
In these two configuration examples, you cannot use the MWA API to determine whether the element e is present or is not present.
