@label (optional) Provides a name or label for an element. The value may be any string. Value of datatype string. att.commonPart
@mimetype (optional) Specifies the applicable MIME (multimedia internet mail extension) type. The value should be a valid MIME media type defined by the Internet Engineering Task Force in RFC 2046. Value of datatype string. att.internetmedia
@n (optional) Provides a number-like designation for an element. Value conforms to token . att.common
@subtype (optional) Provide any sub-classification for the element, additional to that given by its type attribute. Value of datatype NMTOKEN. att.typed
@target (optional) Allows the use of one or more previously-undeclared URIs to identify passive participants in a relationship; that is, the entities pointed "to". One or more values from data.URI , separated by spaces. att.pointing
@targettype (optional) Characterization of target resource(s) using any convenient classification scheme or typology. Value of datatype NMTOKEN. att.pointing
@type (optional) Characterizes the element in some sense, using any convenient classification scheme or typology. Value of datatype NMTOKEN. att.typed
@xlink:actuate (optional) Defines whether a link occurs automatically or must be requested by the user. Allowed values are: " onLoad" (Load the target resource(s) immediately.), " onRequest" (Load the target resource(s) upon user request.), " none" (Do not permit loading of the target resource(s).), " other" (Behavior other than allowed by the other values of this attribute.) att.pointing
@xlink:role (optional) Characterization of the relationship between resources. The value of the role attribute must be a URI. Value conforms to data.URI . att.pointing
