Property accessors provide access to an object's properties by using the dot notation or the bracket notation.

The additive attribute controls whether or not an animation is additive.

The grouping ( ) operator controls the precedence of evaluation in expressions. It also acts as a container for arbitrary expressions in certain syntactic constructs, where ambiguity or syntax errors would otherwise occur.

The unicode-range attribute defines the range of ISO 10646 characters possibly covered by the glyphs in a font.

The yChannelSelector attribute indicates which color channel from in2 to use to displace the pixels in in along the y-axis.

The x1 attribute is used to specify the first x-coordinate for drawing an SVG element that requires more than one coordinate. Elements that only need one coordinate use the x attribute instead.

The u1 attribute specifies list of Unicode characters (refer to the description of the unicode attribute of the <glyph> element for a description of how to express individual Unicode characters) and/or ranges of Unicode characters, which identify a set of possible first glyphs in a kerning pair.

The xml:lang attribute specifies the primary language used in contents and attributes containing text content of particular elements.

The vector-effect property specifies the vector effect to use when drawing an object. Vector effects are applied before any of the other compositing operations, i.e. filters, masks and clips.

The Intl.PluralRules object enables plural-sensitive formatting and plural-related language rules.
