Yes, they should.  Failing to declare the namespace can cause problems
in various situations.

The declaration could be added when the metadata is added to the file.
We would still need to fix the files already in the collection that have
this problem.  Using my SVGscan script, a list of SVG files that don't
internally declare the namespace can be obtained like this:

  python svgscan.py -none -warn=no_namespace .

There are 237 in release 0.17, not counting the 1375 star_*step.svg
files.
