How is the Help facet in the Form Layout Row control used? My guess is that you can put something like a computed field in it, and see the value displayed as help somehow when you view the page in a browser. So far, I can't see that, either as static text or hover help. I'm doing:
<xp:text escape="false" id="computedField5" xp:key="help">
What's the right way to use this facet?
