7.2 Intrinsic XamlType Information Items

  • Article

The following sections define special types used for processing Xaml Instances.

Many of the XamlType Information Item properties are somewhat specialized – the majority of types use the same values for most of the properties. To make it easy to see the distinguishing features of each type, only the properties that differ from the norm are listed. Table 17 shows the values that properties have in the case where their type definition does not specify a value.
