The <title> element provides an accessible, short-text description of any SVG container element or graphics element.

The textual content for a <text> SVG element can be either character data directly embedded within the <text> element or the character data content of a referenced element, where the referencing is specified with a <tref> element.

The <polygon> element defines a closed shape consisting of a set of connected straight line segments. The last point is connected to the first point.

The <font-face-name> element points to a locally installed copy of this font, identified by its name.

Operator precedence determines how operators are parsed concerning each other. Operators with higher precedence become the operands of operators with lower precedence.

The <pattern> element defines a graphics object which can be redrawn at repeated x- and y-coordinate intervals ("tiled") to cover an area.

The <feSpecularLighting> SVG filter primitive lights a source graphic using the alpha channel as a bump map. The resulting image is an RGBA image based on the light color. The lighting calculation follows the standard specular component of the Phong lighting model. The resulting image depends on the light color, light position and surface geometry of the input bump map. The result of the lighting calculation is added. The filter primitive assumes that the viewer is at infinity in the z direction.

The <font-face-uri> SVG element points to a remote definition of the current font.

The instanceof operator tests to see if the prototype property of a constructor appears anywhere in the prototype chain of an object. The return value is a boolean value. Its behavior can be customized with Symbol.hasInstance.

The amplitude attribute controls the amplitude of the gamma function of a component transfer element when its type attribute is gamma.
