The formatter is ONLY "obliged to respect the *inherent* direction
properties..." IF it claims to be of a conformance level fo XSL that
includes this functionality. See section 8 last paragraph and B.3. I do not
believe that FOP claims "extended conformance" which is required for the
functionality described below.

Be careful, you may not need <fo:bidi-override> if I have guessed your
intent from the subject of your message.
As I understand XSLFO, the formatter is obliged to respect the *inherent*
direction properties of the Unicode characters you have in your formatted
stream.
<fo:bidi-override> is just that ... it *overrides* the inherent
directionality of the Unicode characters.
If you are mixing right-to-left Arabic characters with left-to-write
Western European characters, you do *not* use <fo:bidi-override>.
Consider the stylesheet writer writing a stylesheet for global use, taking
care to properly specify writing-direction-dependent properties so as to
work properly with all scripts. It would be untenable to have to look
inside the data to know when the stylesheet would have to control
directionality of characters ... therefore it *has* to be the formatter's
responsibility to address the directionality of Unicode characters.
Now, if you wanted to display Arabic right-to-left characters
left-to-right, *then* you would use <fo:bidi-override>.
I hope this helps.

p.s. as for FOP, I have no idea if it respects directionality or not ...
sorry
