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 here

[source]attribution goes here[/source]

[/dd]

[/dlentry

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

 Any suggestions?
