[XeTeX] Syriac: Text Direction

[Thomas Thackery]

Thank you for the help.  The "Script=" solved the vowel and  
connection issues.  The last remaining bit is to get it to display  
right-to-left; i.e., each word is written correctly, but the sentence  
as a whole is written in the wrong direction.  In the attached  
example, the text on top (from Accordance) correctly shows the RTL.   
The bottom example, from Xe(La)Tex; displays improperly from left-to- 
right.

In addition to the misplaced vowels, you're not getting proper Syriac
connecting forms of the letters. This is because you need to specify
the Syriac script shaping behavior in your font declaration:

     \newfontfamily{\syr}[Script=Syriac,Scale=1.2]{Estrangelo Talada}

should do it.
