Yes.  It ought to all be conforming SVG, but I know that much of
it isn't, and this is something that needs to be fixed.

You need to add the correct document type: many of the files are
SVG 1.0 rather than SVG 1.1, and you will get a validation failure
if you add the wrong one (because the DTD will conflict with the
'version' attribute).

The SVG 1.0 and SVG 1.1 specs have appendices on conformance
criteria.  Have you looked at these?  It's similar to what you
are doing, but not quite the same, and you are probably getting
validation errors on many files that are in fact conformant.
