def write_file(self, filepath: str | Path, default_permissions: Permissions | None = None) -> None:
    """
    Write the finished XML to a file.

    Args:
        filepath: where to save the file
        default_permissions: permissions to overwrite `Permissions.PROJECT_SPECIFIC_PERMISSIONS`

    Attention:
        If the parameter `default_permission` is not filled
         and no permissions were assigned to values and resources,
         the default permissions (DOAP) on DSP will be applied.
         If the default permissions (DOAP) are not changed via DSP-API,
         only project members and admins have view permissions.
         In the near future,
         custom DOAPs will be able to be set in the project JSON file (ongoing DSP-TOOLS project).
         At that time this parameter will be deprecated.

         **This will not influence individually assigned permissions, for example
         `Permissions.RESTRICTED` will stay restricted even if your default is set to `Permissions.OPEN`.**

    Warning:
        if the XML is not valid according to the schema

    Examples:
        ```python
        root.write_file("xml_file_name.xml")
        ```

        ```python
        # To overwrite `Permissions.PROJECT_SPECIFIC_PERMISSIONS`
        root.write_file("xml_file_name.xml", Permissions.OPEN)

serialise

Create an lxml.etree._Element with the information in the root. If you wish to create a file, we recommend using the write_file method instead.

Parameters:

Name Type Description Default
default_permissions Permissions | None

permissions to overwrite Permissions.PROJECT_SPECIFIC_PERMISSIONS

 None

Returns:

Type Description
_Element
