Slide 41 of 50

In the example on this slide, the content actually has markup to perform the same role as the its:dir attribute. We use a global rule to indicate that all direction attributes with a value of rtlText are equivalent to its:dir="rtl". (In an actual implementation, you would probably want to define rules for all possible values of the direction attribute - we kept things simple for the example.)
