The specularExponent attribute controls the focus for the light source. The bigger the value the brighter the light.

The name attribute specifies either the name of a color profile or a font face.

The primitiveUnits attribute specifies the coordinate system for the various length values within the filter primitives and for the attributes that define the filter primitive subregion.

The repeatCount attribute indicates the number of times an animation will take place.

The ry attribute defines a radius on the y-axis.

The spreadMethod attribute determines how a shape is filled beyond the defined edges of a gradient.

The stemh attribute indicates the horizontal stem width of the font.

The pointsAtY attribute represents the y location in the coordinate system established by attribute primitiveUnits on the <filter> element of the point at which the light source is pointing.

The transform-origin SVG attribute sets the origin for an item's transformations.

The textLength attribute, available on SVG <text> and <tspan> elements, lets you specify the width of the space into which the text will draw. The user agent will ensure that the text does not extend farther than that distance, using the method or methods specified by the lengthAdjust attribute. By default, only the spacing between characters is adjusted, but the glyph size can also be adjusted if you change lengthAdjust.
