if, then, else alignment for imageobject

[Sean Wheller <sean@enbaya.co.za>]

Hi,

I have requirement to align images to the outsides of facing pages.
Hence all imageobjects on an even page are aligned left and on an odd page, 
right.

Now I can manually set the @align on each imagedata, but as content is 
modified, it will cause pictures to move position. An image that was once on 
an even page may move to an odd page, and the other way around.

Is there a way to implement some logic that will automatically handle this 
during the transformation to XSL-FO so that maintenance becomes easier. 
Perhaps an additional value for the @align (align="auto"), and then XSL 
processing logic that will decide based on the page number whether the image 
is right or left.
