For <mask>, maskContentUnits defines the coordinate system in use for the content of the element.

| Default value | userSpaceOnUse |
| Animatable | Yes |
userSpaceOnUseThis value indicates that all coordinates inside the <mask> element refer to the user coordinate system as defined when the mask was created.
objectBoundingBoxThis value indicates that all coordinates inside the <mask> element are relative to the bounding box of the element the mask is applied to. A bounding box could be considered the same as if the content of the <mask> were bound to a "0 0 1 1" viewBox.
