Some of the definitions in a definition-list have clearly-defined attributions, for example ISO. It seems logical, if the goal is to produced a set of structured and searchable files, to use something like

[dlentry]

   [dt]name of term goes here[/dt]

   [dd]definition of term goes her

      [source]attribution goes here[/source]

   [/dd]

[/dlentry]

[source] is clearly not the element to use here, though; nor is [author].

Any suggestions?
