Attribute	Description
accesskey	The keyboard access key that puts the link in focus. When the link is in focus, pressing the Enter key is equivalent to clicking the link.
charset	The character set used to encode the specified URL. If not specified, this value defaults to ISO-8859-1.
coords	The position and shape of the hot spot on the screen used for the output link (for use in client-side image maps). The number and order of comma-separated values depends on the shape being defined. For example, to define a rectangle, use coords="left-x, top-y, right-x, bottom-y". To define a circle, use coords="center-x, center-y, radius". To define a polygon, use coords="x1, y1, x2, y2, ..., xN, yN", where x1 = nN and y1 = yN. Coordinates can be expressed in pixels or percentages, and represent the distance from the top-left corner of the image that is mapped. See also the shape attribute.
dir	The direction in which the generated HTML component is read. Possible values include "RTL" (right to left) or "LTR" (left to right).
