Attributes

The IS_TRUE element has the following attributes:

Table 1. Attributes of the IS_TRUE Element
Attribute Name	Required	Default	Description
`NAME`	Yes		The name of the `SERVER_INTERFACE` instance to use as the source of the property value.
`PROPERTY`	Yes		The name of the property being accessed. It must be a Boolean value.

In the majority of cases the NAME and PROPERTY combination will reference a display-phase server interface property. However when a page submits to itself using an ACTION_CONTROL with a child LINK element that has the PAGE_ID set to THIS (e.g., a search page), properties of the action-phase server interface can be referenced. When the page is first displayed the action-phase server interface will not be in scope and the property is treated as if its value is false. When the page is submitted, the action-phase server interface will be in scope and the referenced property will be evaluated as normal.
