Directionality with <pc> and <sc/>

Hi all,

 

Has anyone implemented the dir attribute in <pc> and <sc>?

 

Given this:

 

The default value for it is "The value of the dir attribute of the lowermost <source>, <target>, or <pc> element, in which the element in question is located."

 

<segment>LLL<pc id='1' dir='rtl'>RRR<sc id='2'/>RRR</pc>???<pc id='3'>???</pc>???<ec startRef='2'/>LLL</segment>

 

- Where does the sequence of RTL text stops? At the first </pc> or at the <ec/>?

 

- Is the second <pc> rtl or ltr?

 

 

The bottom line: I'm not sure how inheritance is not going to work inside <source> or <target> because of the overlapping codes and the isolated codes.

 

Regards,
