External references in test suites

Hi,

in a separate discussion, it's been noticed that a number of tests in 
the test suite reference media files that are located under 
http://media.w3.org/.

Is that something we want? It would seem to me that it would be best if 
the test suite were self contained.

Any thoughts?
