Adding attributes to child components in a behavior.

[Warren Bell]

Is there a way to add attributes to child components in a behavior that
is added to a page? I want to create a behavior that is added to a page
that adds some js to the header and then adds some js in an onfocus
attribute of each child form component on the page. I have the list of
child form components, but can't figure out how to add the attribute to
the components.
