===== The Element ===== ==== Definition and Usage ==== The [[link|]] element defines a relationship among media and composite objects. A [[link|]] element may have an //id// attribute, which uniquely identifies the element within a document, and must have an //xconnector// attribute, which refers to a connector URI. The referred [[causalconnector|]] element defines the relation without specifying who plays the relation roles. Who plays is defined using [[bind|]] elements, children of the [[link|]] element. ==== Syntax ==== ^ Element ^ Attributes ^ Content ^ Parent ^ | [[link|]] | //id//, __//xconnector//__ | ([[linkparam|]]*, [[bind|]]+) | [[body|]] or [[context|]] or [[switch|]] | ==== Attributes ==== ^ Name ^ Value ^ Description ^ | //id// | It may receive any string value that begins with a letter or an underscore and that only contains letters, digits, <".">, and <"_">. | The //id// attribute uniquely identifies the element within a document. | | //xconnector// |
