The font-weight and font-style attributes have the same purpose as the equivalent descriptors in CSS. In the example above the first and most important to be defined is font-family, the value of which can then be referenced in CSS and SVG font-family properties. It defines basic properties of the final font such as weight, style, etc. The element is the SVG equivalent of the CSS declaration. There are several accompanying attributes that help further define the basic glyph-box layout. The value 1000 sets a reasonable value to work with. The horiz-adv-x attribute determines how wide a character is on average compared to the path definitions of the single glyphs. This bears an id attribute, to enable it to be referenced via a URI (see below).
