They are needed to inform TOC generation and PDF Bookmark gen among probably other things.

rtfm … here's what the MIF Reference says about , in case anyone else is ever curious:
Document File Info
For version 7.0 and later, FrameMaker stores file information in packets (XMP) of encoded data. This data can be used by applications that support XMP. In MIF these data packets are expressed in the statement. This data is generated by FrameMaker in an encoded form, and you should not edit the information. Note that this information corresponds to the values of fields in the File Info dialog box. It also corresponds to the data in the statement. However, unlike , this XMP data also includes the values of the File Info dialog box default fields for Creator, Creation Date, and MetaData Date.
