A default ``Creator``, ``Producer``, and ``CreationDate`` are added, though the user metadata may override it. The date may be the current time, or a time set by the ``SOURCE_DATE_EPOCH`` environment variable. Metadata is verified to have the correct keys and their expected types. Any unknown keys/types will raise a warning. Parameters ---------- backend : str The name of the backend to use in the Producer value. metadata : dict[str, Union[str, datetime, Name]] A dictionary of metadata supplied by the user with information following the PDF specification, also defined in `~.backend_pdf.PdfPages` below. If any value is *None*, then the key will be removed. This can be used to remove any pre-defined values. Returns ------- dict[str, Union[str, datetime, Name]] A validated dictionary of metadata.
