This extension is used to see which properties are available for different Plesk objects (such as domains, subdomains and webusers). In the descriptor of objects properties, which you can retrieve using the **site/get-physical-hosting-descriptor** operation, each property has the **extension** element. Inside the extension element there is either the **service** node, or one or several **level** nodes. The **extension** node of physical hosting property can be represented graphically as follows:

- The **service** node is *required* if the property is a service. It specifies if the service is a hosting property of a managed object defined by a child node. The node can contain several or all of the following child nodes in the preassigned order: - the **domain** node specifies if the property is visible when managing subscriptions. - the **subdomain** node specifies if the property is visible when managing typical subdomains. - the **webuser** node specifies if the property is visible when managing web users. - The **level** node is required if the property is not a service. It specifies if the property is visible when managing an object. The **level** node can have one of the following values: - *domain*. The property is visible when managing subscriptions. - *subdomain.* The property is visible when managing typical subdomains. This extract from a physical hosting descriptor shows that the service property *asp* is available for subscriptions (domains), subdomains and web users.

<property>
  <name>asp</name>
  <type>boolean</type>
  <writable-by>admin</writable-by>
