The most basic of links in WebCGM is a simple hyperlink, with no behaviors, and with no object targetting within the CGM.

WebCGM further allows the specification or selection of particular objects within a target WebCGM instance. Object selection within a link target may be either by the (unique) value of the object's APS Id parameter, or by the (possibly non-unique) value of an APS attribute element of type 'name'.
