LoadWorldResourceDocument(world_document,file$,repair=0)
Requires Extended mode.
Opens a resource from the world’s staged workspace when present, otherwise from disk. This includes undone and newly extracted sources that have not been saved. Dependency validation and LoadResourceDocumentAsync use the workspace snapshot. The returned ordinary resource-document handle is an independent editable draft; free it with FreeResourceDocument. Saving through the coordinated world-edit commands records the source and scene bindings together.
