I have an ECMAScript object located in a library. What is the proper
syntax to call the functions in this object from a policy in Policy
Builder? I know that I can use the XPATH("es:ldapSearch ... ") syntax if
the ECMAScript is located in the same driver as the policy. However, I
don't know what the equivalent is for scripts located in a library (at the
Driver Set level).

I tried using the "New -> Include Before" menu option in Policy Builder as
described in the documentation, but this (apparently) only allows you to
select XSLT and Policies (not ECMAScript).

I can get things working with a local object, but I'm trying to leverage
the benefits of a library.
