The <pattern> SVG 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 <feTurbulence> SVG filter primitive creates an image using the Perlin turbulence function. It allows the synthesis of artificial textures like clouds or marble. The resulting image will fill the entire filter primitive subregion.

The <glyphRef> SVG element provides a single possible glyph to the referencing <altGlyph> substitution.

The <feSpotLight> SVG filter primitive defines a light source that can be used to create a spotlight effect. It is used within a lighting filter primitive: <feDiffuseLighting> or <feSpecularLighting>.

The <feComposite> SVG filter primitive performs the combination of two input images pixel-wise in image space using one of the Porter-Duff compositing operations: over, in, atop, out, xor, lighter, or arithmetic.

The <svg> SVG element is a container that defines a new coordinate system and viewport. It is used as the outermost element of SVG documents, but it can also be used to embed an SVG fragment inside an SVG or HTML document.

The <view> SVG element defines a particular view of an SVG document. A specific view can be displayed by referencing the <view> element's id as the target fragment of a URL.

The marker-end attribute defines the arrowhead or polymarker that will be drawn at the final vertex of the given shape.

The fill-opacity attribute is a presentation attribute defining the opacity of the paint server (color, gradient, pattern, etc.) applied to a shape.
