Feature request - support intellisense in WindowsStoreProxy.xml files. Follow

Here's a small feature request for ReSharper 8 - would it be possible to support intellisense when editing WindowsStoreProxy.xml file in Windows 8 projects? These files are used for testing in-app purchases and having fully working intellisense/autocomplete will help a lot.
Here's a specification and xsd schema of the file structure:

Thanks!
