Clarify usage of Google copyright in xml sourcecode

[scabug]

The following sourcecode contains Google copyright statements:

scala-2.8.0.RC1-sources\src\library\scala\xml\Elem.scala
Line 18: * Copyright 2008 Google Inc. All Rights Reserved.
Line 41: * Copyright 2008 Google Inc. All Rights Reserved.

scala-2.8.0.RC1-sources\src\library\scala\xml\MetaData.scala
Line 18: * Copyright 2008 Google Inc. All Rights Reserved.
Line 72: * Copyright 2008 Google Inc. All Rights Reserved.

They are from Burak Emir after he moved to Google. I'm not sure if this is just something that's been added automatically by his editor, but it would be nice to get a clarification since it's not mentioned in the Scala license.

Oops. I think I've seen other places in the source where there are non-EPFL copyrights, but I can't find them at the moment. IIRC the contributor agreement doesn't require that copyright ownership be transfered to the EPFL, only that it be given an appropriate license to the code.

The copyright notice was not added by accident.

The patch was built in 20% time while I was already working for Google, using Google's resources. The patch was formally reviewed and approved and Google is ok with it being part of Scala and people using, distributing, etc... it under the Scala license.

That is why the copyright notice is there. See "committed to open source" in http://investor.google.com/corporate/code-of-conduct.html

Hope this helps!

Maybe it would be possible to add some additional explanation, so that the next person reading the code doesn't get a heart attack. :-)
