Dear Maintainer,


When processing SVG file with following doctype declaration:

<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/
1.1/DTD/svg11.dtd">

xmllint complains

file:///usr/share/xml/svg/svg11.dtd:2278: validity warning : Attribute space of element style: already defined


It seems that such things shouldn't happen and so widely-used DTD as
SVG should be processed without warnings.
