Is there any way to register custom text variable type in InDesign?

Question

Like here few default types are predefined , If someone wants to register a new type how can it be achieved.

To follow up, there is indeeed a matching service kTextVariableServiceID. The interface ID is IID_ITEXTVARIABLESERVICE_PRIVATE though and as the name suggests it is not included in the SDK.

I guess it was too much trouble to handle documents with a new text variable type backed by a missing plug-in.

As you tagged this with "SDK": Enumerations are extensible by C++ plug-ins, it is just another declaration resource snippet similar to adding a JS property or class in the ScriptInfo database aka object model. Not all of the enumerations are backed by extensible features, though - some are just mapped to enumerations at the C++ side.

The typical approach would be a matching entry in the internal service registry, could also be a startup service that registers them in a factory.

If you meant to include that in "any way" I'd suggest to first have a look at the SDK programming guide and to search thru the headers for related constants and interfaces.
