Users, Roles, VisitorGroups	Defines which users, roles, and visitor groups have access rights.	No user has access to ContentType.
Access	Defines the level of access to grant.	ContentTypes support access level Create only.

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 either a typed content directly or it can be the type of an interface or a base class. At registration, registered types that can be assigned to the specified type are included. For example, if an interface is specified in an Include list, then typed pages that implement the interface are included.

The following image shows how Include differs from IncludeOn and how they are mapped in admin view.

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

The following image shows how Exclude differs from ExcludeOn and how they are mapped in admin view.

If types are not registered in Include, then registered page types are available except the types in the Exclude specifications.
If types are registered in Include, then those types are available except the types in the Exclude specifications.

The follwing image shows how Availability is mapped to settings in admin view.
