I generate multi-page Postscript files, for example of Book morphs. The goal is to crete Adobe Document Structuring Conventions compliant, but this is currently not the case.
Document Structuring Conventions, or DSC, is a set of standards for PostScript, based on the use of comments, which primarily specifies a way to structure a PostScript file and a way to expose that structure in a machine-readable way. A PostScript file that conforms to DSC is called a conforming document. https://en.wikipedia.org/wiki/Document_Structuring_Conventions
