Even so they can be converted to each other. Furthermore SVG1.2T has the following sentence: "Other W3C specifications are expected to be revised over time to remove these duplicate descriptions of the escaping procedure and to refer to IRI directly."

The differences between a URL, URI, and IRI as defined by the various
standards bodies are irrelevant to authors.  CSS doesn't care - it
takes whatever browsers choose to accept as a "url".  The grammar of
url() is basically just "url(, then anything that's not a )
character", which encompasses all of the various silly terms.  We just
use the "<url>" grammar token for it, because that's the term most
familiar to authors.
