fo:text-align="end"

The tag above, from §15.5.5 and indirectly from XSL  §7.16.9 is said to do 
the following;
end: "Specifies that the content is to be aligned on the end-edge in the 
inline-progression-direction."

Now see the attached test doc. (odt and xml are the same).

There is some RTL text, Easy to spot. And I set the text-align to 'end' 
which to me indicates that the alignment is left for that RTL text.
So, at least one of the two RTL texts should be left aligned. I'm even 
thinking both of them.

None of the ODF implementations I tried actually do this, except KWord2 
but I'm unsure what the correct bahavior is now.

Can someone explain the reasoning and expected behavior here?

Thanks!
