This comes from XML (actually, Namespace in XML), not from SVG.

DS> In general SVG attributes should be in the SVG namespace, no? 

No.

"A default namespace declaration applies to all unprefixed element names within its scope. Default namespace declarations do not apply directly to attribute names; the interpretation of unprefixed attributes is determined by the element on which they appear. "

DS> The

No, because they are not prefixed.
