Validating Cross-domain Access Policy Files
The latest Silverlight Spy update (version 2.0.0.12) contains an enhanced version of the Cross-domain Access Policy File Validator. Given a domain it will try to load the clientaccesspolicy.xml and/or crossdomain.xml. Once found, the files will be validated using an XML schema and are available for detailed inspection in an xml editor.
New features include editing your own policy file and have the Policy File Validator check your policy file for errors and warnings.

Fun fact: did you know the crossdomain.xml from Flickr (domain: api.flickr.com) is not valid according to the schema provided by Adobe? The policy file still works though, but it's not valid.
You can find the Policy File Validator in the Tools menu.

Nice work. In addition to validation of the crossdomain.xml file. I know Google Picasa Web Albums doesn't even have the crossdomain.xml file in the right place. It seems flash can handle this, but Silverlight needs the file to be in the root.
