-*- Mode: text; -*- Extensible Stylesheet Language: Formatting Objects ================================================================================ * XSL:FO documents have no known metadata semantics. * XSL:FO documents created from documents with known metadata semantics (like HTML, MathML, DOCBOOK) lose the metadata. * XSL:FO documents are specific to one media type. => XSL:FOs lack portability. * XSL:FO presentation cannot be inherently controlled by the user (this applies to all media -- even when printing, you want to be able to control things like font size, contrast, etc). => XSL:FOs are bad for accessibilitity. * XSL:FO does not provide substantially more power than existing presentation languages (e.g. PDF, DSSSL) => XSL:FO is a weak language in its field.
