Until now ABML tags had to have their attributes enclosed in double quotes like so:

<tt ref=”123″>Turn to 123</tt>

Now you are permitted to alternatively use single quotes like so

<tt ref=’123’>Turn to 123</tt>

This may be useful for SEL script writers who wish to use double quotes inside their tags instead of being forced into single quote useage only (yes I am looking at making variables intrerpolate inside double quoted strings one day, all being well, this is a step toward that).
