Element: default

Description: In GraphML there may be data-functions attached to graphs, nodes, ports, edges, hyperedges and endpoint and to the whole collection of graphs described by the content of <graphml>. These functions are declared by <key> elements (children of <graphml>) and defined by <data> elements. The (optional) <default> child of <key> gives the default value for the corresponding function. Occurence: <key>.

Type: default.type

Complex type for the <default> element. default.type is mixed, that is, data may contain #PCDATA. Content type: extension of data-extension.type which is empty per default.  Type is final.
