XML Projects

Now that Whidbey is almost out the door, we've started planning our next release.  A number of customers have told us that they would like to have XML Projects.  However, nobody explained exactly what that meant.  So I'd like to investigate this a bit further.  Do you have a need for an XML Project?  If so, what kind of functionality are you looking for, is it just a collection of files or something more?  Would you need a generic XML project or various flavors - XSLT, XSD, etc.?
