• W3C XSL-FO 1.0 Standard

W3C XSL-FO 1.0 Standard

One of FOP's design goals is conformance to the W3C XSL-FO 1.0 standard, which specifies three levels of "conformance": basic, extended, and complete. Although FOP does not currently conform to any of these levels, it is nevertheless a useful work-in-progress for many applications. The information presented here demonstrates FOP's progress toward the goal of conformance, which progress consists of implementation of specific objects and properties in the standard. The information presented is useful not only to the developers as a sort of "to do" list, but also for setting proper expectations for users and potential users.

In the tables below, blue indicates support at the specified level of conformance, and red indicates a lack of support.
