xlink:type

Type of Link

The kind of link used with an element. For all elements in this Tag Suite that can take links (except the <mml:math> element), this attribute may be either omitted or set to the word “simple”, which means that the link is a simple, one-ended link. For the <mml:math> element, the attribute may take any value that describes the link type, for example, a “simple” (one-ended) link, a “locator” link, a “title” link, an “extended” (multi-way) link, etc.

Remarks

For all elements (except <mml:math>), the only valid value for the attribute is the word “simple”, but the attribute is optional and may be omitted. For the <mml:math> element, the attribute best practice will restrict the value to one defined in the MathML and XLink specifications; see them for further details.
