5 Xaml Members where [is attachable] is True
A type that defines members whose [is attachable] property is True will list them in a section that begins with “(attachable properties)”. The following FruitBowl type example defines a Children member for which the normal defaults apply. This FruitBowl type also defines an attachable member named ZIndex for which [is attachable] is True. (The other member defaults still apply for ZIndex.)

The name for an attachable member is specified as TypeName.MemberName. This is a syntactical convention to make it clear that this is an attachable property, and to illustrate how the property will look in a Xaml document. The [name] property of the XamlMember Information Item will only contain the MemberName part (the part after the period).
