Detailed Descriptions for the elements in the extension.

Comments

GeneratedFrom is a specialized type of 'derived from'. The expectation is that the initial version of an artifact that was generatedFrom a definition will also complyWith that definition. However, it is possible that subsequent revisions may invalidate 'compliesWith'. Those revisions would not invalidate the 'generatedFrom' assertion.

Also see the notes in the workflow extensions area for more guidance on this element.
