Konrad Windszus commented on JCRVLT-560:
----------------------------------------
Regarding multi-value binary properties: Conceptually this can only work if
either all values are binary references (inline in docview) or not binary
references (given via {{.property}} files). A mixture is impossible as DocView
only allows one type and the order between DocView values and values from
{{.property}} files would be unspecified. Therefore the export should fail with
an exception for such edge case. [~tripod] WDYT?
