Anyone using Profile Scripts with AEP Web SDK implementation?

[wgharper]

I've recently been working on a new implementation of Analytics/Target via the AEP Web SDK, and am in the process of configuring some new activities.  In the past, I've used profile scripts as an easy way to handle complex audience parameters that need some sort of calculation or persistence, but I don't see anything in the documentation that addresses how to reference XDM data in the profile script editor.  Is this even an option with the Web SDK, and if so how would I reference the XDM data when building a script?
