`description`	Human-readable description, if present

`file_size`	Uncompressed file size in bytes
`stored_size`	Size as stored in PDF (compressed), in bytes
`compression`	PDF filter name (e.g. `/FlateDecode`), if compressed
`created`	Creation date in PDF date format
`modified`	Modification date in PDF date format
`pages`	List of pages this attachment is attached to

Note: document-level attachments are attachments which are not attached to any pages. In this case, the pages field is absent.
