==========
This property is defined in the CSS Line Layout Module 3 specification. See 'dominant-baseline'. [css-inline-3]

SVG 2 introduces some changes to the definition of this property. In particular:

* The 'reset-size' value is no longer supported. Any change in font-size resets the dominant baseline table.
* The 'use-script' and 'no-change' values are no longer supported.
* The property is now inherited. (Behavior is effectively unchanged.)

SVG uses the value of the dominant-baseline property to align glyphs relative to the ‘x’ and ‘y’ attributes. For the text-orientation value sideways, the auto value for dominant-baseline is alphabetic; however, for backwards compatibility, the glyphs should be aligned to the ‘x’ and ‘y’ attributes using the value central.
