## Methods

| Definition                                               | Description                                                                                                                                                                                                                                    |
| :------------------------------------------------------- | :--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `UpdateTypeRegistrationProperties (name: string) : bool` | Updates the document's registration parameters for the current document type. Preserves values from parameters that share a name with the previous type. Returns `false` if the document type is non-empty and not included in `DefinedTypes`. |

<Note>
  If you change the document type in a script without calling `UpdateTypeRegistrationProperties`, the registration parameters from the previous type are preserved.
