Symbolic links in Solaris Packages

I'm working on creating a few custom packages for my own internal environment. I have a question that is speciifically related to symbolic links made via package.

After looking at some tips for creating packages, I've installed the software and generated the prototype file - so far so good.

I'm putting the app in, say, /opt/app. I want to make symbolic links from /usr/bin to /opt/app/bin.

I see how to make a link using the "l" (ell) entry type, but I'm unclear on if I can make a link outside of the package installation directory - and if so, the exact syntax of the prototype file entry. The examples I've found all create links within the directory structure of the package installation, not in directories outside of it.
