Specifies the coordinate system for attributes x , y , width , and height .
objectBoundingBox | userSpaceOnUse Specifies the height of the element.
Specifies the coordinate system for the various length values within the filter primitives and for the attributes that define the filter primitive subregion.
objectBoundingBox | userSpaceOnUse Specifies the width of the element.
Specifies the x-coordinate of the element.
Specifies the y-coordinate of the element.
