escaping curly braces in attribute

Okay i feel dumb.  I used to know this:

i need to output 

	onclick="if(foo) {return bar}"

but of course the {}'s are causing errors.
so i tried 

	onclick="if(foo) \{return bar\}"

but that's not it...

anyone?


i suppose xsl:attribute should work...
 but is there another way?
