Why does my DB project's .dbmdl file change even when I make no changes to the project?

Question

I\'m running into a small but weird annoyance that seems to be happening to other people, too (for example, check out the revision history of SEDE). I have a SQL Server 2008

If you delete the .dbml file, it is rebuilt without errors or warnings, so I think it's just a cache file for references, intellisense, etc. I'm going to exclude it from source control.
