The values of xlink:type are not link types, but element types; they indicate
nothing about the link, but only indicate the (attribute) syntax of the
element to which they are attached.  In fact, all of these represent
auxiliary element types except "simple" and "extended", and these so-called
types differ only in syntax.

The true XLink representation of "link types" in the sense you mean is
xlink:role attributes.
