One of Apache™ FOP's design goals is conformance to theW3C XSL-FO 1.1 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.
The following table shows the legend used for the tables below:
| yes | indicates conformance |
| partial | indicates partial conformance |
| no | indicates a lack of conformance |
| na | indicates that the item is "not applicable" to FOP usually because FOP supports only visual media |
The following is a summary of FOP's current support for the standard XSL-FO objects.
| Citation | Object Name | XSL-FO Conformance Level | FOP 1.0 | FOP 1.1 | FOP 2.0 | FOP 2.3 | FOP 2.4 to 2.8 | FOP 2.9 to 2.10 | FOP dev | Comments |
