Source file references
Here you select which version of the source document will be used for the conversion.
'Use the latest version of the referenced files', DocPublication will use the latest version of the archived document.
'Using the referenced version of the referenced files (as built)', DocPublication will use the version referenced in the active document (part or assembly).
The option Use the version in the local cache when launching the task allows to export the local version present in the document vault when the task is launched by the user.
