The arabic-form attribute indicates which of the four possible forms an Arabic glyph represents.

The <cursor> SVG element can be used to define a platform-independent custom cursor. A recommended approach for defining a platform-independent custom cursor is to create a PNG image and define a cursor element that references the PNG image and identifies the exact position within the image which is the pointer position (i.e., the hot spot).

The cap-height attribute defines the height of uppercase glyphs of the font within the font coordinate system.

The orientation attribute indicates that the given glyph is only to be used for a particular text direction, i.e., horizontal or vertical.

The v-ideographic attribute indicates the alignment coordinate for glyphs to achieve ideographic baseline alignment for vertically oriented glyph layouts. The value is an offset in the font coordinate system relative to the glyph-specific vert-origin-x attribute.

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

The <font-face> SVG element corresponds to the CSS @font-face rule. It defines a font's outer properties.

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

The <font-face-src> SVG element corresponds to the src descriptor in CSS @font-face rules. It serves as container for <font-face-name>, pointing to locally installed copies of this font, and <font-face-uri>, utilizing remotely defined fonts.
