Identifies 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 uses the fixed (unchanging) value “ 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.
For all elements (except <mml:math>), the value of the attribute is the word “ simple ” and cannot be changed; it is intended for use by software. For the <mml:math> element, best practice will restrict the value to one defined in the MathML and XLink specifications; see them for further details.
