The pointsAtZ attribute represents the z location in the coordinate system established by attribute primitiveUnits on the <filter> element of the point at which the light source is pointing, assuming that, in the initial local coordinate system, the positive z-axis comes out towards the person viewing the content and assuming that one unit along the z-axis equals one unit in x and y.

The side attribute determines the side of a path the text is placed on (relative to the path direction).

The maskContentUnits attribute indicates which coordinate system to use for the contents of the <mask> element.

The stroke-miterlimit attribute is a presentation attribute defining a limit on the ratio of the miter length to the stroke-width used to draw a miter join. When the limit is exceeded, the join is converted from a miter to a bevel.

The stop-color attribute indicates what color to use at a gradient stop.

The r attribute defines the radius of a circle.

The strikethrough-position attribute represents the ideal vertical position of the strikethrough. The strikethrough position is expressed in the font's coordinate system.

The specularConstant attribute controls the ratio of reflection of the specular lighting. It represents the ks value in the Phong lighting model. The bigger the value the stronger the reflection.

The unicode attribute specifies one or more Unicode characters indicating the sequence of Unicode characters which corresponds to a glyph.

The targetX attribute determines the positioning in horizontal direction of the convolution matrix relative to a given target pixel in the input image. The leftmost column of the matrix is column number zero. The value must be such that: 0 <= targetX < order X.
