XHTML+MathML+SVG xmlns in sample

In section 3.1 of 'An XHTML + MathML + SVG Profile' working draft, the SVG
fragment of the example has an xmlns attribute as follows:

xmlns="http://www.w3.org/2000/svg"

Is this what the editor really intended, or just a typo of this one?

xmlns:svg="http://www.w3.org/2000/svg"
