Though XFC implements the greater part of the W3C recommendation, it does not support all XSL-FO features. Below is a list of the current major limitations of XFC.
leader element is only partly supported.
marker elements are not supported.
writing-mode property is not supported (value
lr-tb is assumed).
The conformance level of XFC may be improved in future versions, however it must be stressed that a full conformance cannot be achieved due to the own limitations of its output formats.
