Apparently Erik and chaals disagree

"When we first implemented
SVG in the browser, we included strict namespace requirements. Due to a
small handful of customer requirements (important to us as they were our
customers) to support broken content, we actually changed that pretty
quickly and introduced some gentler error-correction in a point update.
Long ago in the beta process for Opera 9.5 (which has been commonly used
for SVG since its support is significantly advanced compared to Opera 9)
we went back to the stricter behaviour, which we have maintained in the
9.5 and subsequent releases, with no outcry about the Web not working. It
is pretty clear to us that in practice SVG does work with the relatively
strict requirements of XML, and in particular with the XML namespaces
spec, and we see no good reason to break that. "

Jeff
