feature request #9539
Implement availableFor for ExtensionType, MarkerType, AnnotationType and IdentifierType
Similar to Features #9027
We may need to decide for all existing Types what they should support by default. Also we need to write an update script for the default values and for already existing uses (what ever usage exists in a database we expect the availableFor shold be set for the combination in this database).
The field should not be managed by term server.
Maybe we need a new DefinedTermBase subclass AvailableForTerm or even 2 AvailableForIndentEntity and subclassing from the previous AvailableForAnnotatableEntity. These may offer boolean methods for each availableFor class
