AvailableContentTypesAttribute

Use AvailableContentTypesAttributes to set which content types are available under a content instance; it has the following configurable properties.

Property	Description	Default value
`Availability`	Defines whether all or no content types are available. If you set none, other settings on the attribute is ignored.	Availability.All
`Include`	A type array of typed content to specify which content types are available under a content instance of the type with the attribute.	Type[0]
`Exclude`	A type array of typed content to specify which content types are not available under a content instance of the type with the attribute.	Type[0]
`IncludeOn`	States that the content with this attribute is available under the typed content in the type array.	Type[0]
`ExcludeOn`	States that the content with this attribute is not available under any of the typed content in the type array.	Type[0]

The types given on Include, Exclude, IncludeOn, and ExcludeOn can be typed content directly, or it can be the type of an interface or a base class. Registered types that can be assigned to the specified type are included at registration. For example, if an interface is specified in an Include list, then typed pages that implement the interface are included.

Include differs from IncludeOn in the following ways

Include excludes typed content except that which is specified.
IncludeOn does not exclude any content type for types that have all content types available.
