The <<.def namespace>> [[variable|Variables]] is used internally by [[HTML|HyperText Markup Language]] widgets to keep track of the correct namespace for the [[DOM|Document Object Model]] elements they generate.

An `svg` or `math` element supplies a distinct namespace for itself and any child elements it contains.
