The y2 attribute is used to specify the second y-coordinate for drawing an SVG element that requires more than one coordinate. Elements that only need one coordinate use the y attribute instead.

The to attribute indicates the final value of the attribute that will be modified during the animation.

The writing-mode attribute specifies whether the initial inline-progression-direction for a <text> element shall be left-to-right, right-to-left, or top-to-bottom. The writing-mode attribute applies only to <text> elements; the attribute is ignored for <tspan>, <tref>, and <textPath> sub-elements. (Note that the inline-progression-direction can change within a <text> element due to the Unicode bidirectional algorithm and properties direction and unicode-bidi.)

The xlink:arcrole attribute specifies a contextual role for the element and corresponds to the RDF Primer notion of a property.

The u2 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 second glyph in a kerning pair.

The visibility attribute lets you control the visibility of graphical elements. With a value of hidden or collapse the current graphics element is invisible.

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

SVG images can be used as an image format, in a number of contexts. Browsers support SVG images in:

SVG elements can be modified using attributes that specify details about exactly how the element should be handled or rendered.

The x attribute defines an x-axis coordinate in the user coordinate system.
