As of MODX Revolution version 2.2.5, the Access Policy export feature is fixed! This was a huge PITA for a long time, because who wants to go through the list of 174 permissions hunting for the right ones to check off? The Access Policy Templates are a great help, of course, but the Content Editor Policy never had the permissions I needed for my clients. Now, I can export and import them at will, and IT WORKS LIKE A DREAM!
How to Export Your Own Access Policies
This is really easy, but also easy to miss. In the Manager, go to the top menu "Security" » "Access Controls". On that page, select the "Access Policies" tab. Right-click on the Policy you wish to export, and choose "Export Policy". You'll be prompted to download an XML file.

How to Import an Access Policy
When it's time to setup a new site, navigate to the same page and click the "Import" button. Choose the XML file and voila! A new Access Policy will be created with the settings from your XML file! Note: on older versions of MODX this feature was buggy. If you're using 2.2.5 sites on both ends of the transaction, it should work perfectly - it did for me!
