(Thanks to @doublem for flagging this up)
Having checked with Eastgate, I’ve corrected my notes on the Ziplinks syntax as regards the backlink mark-up.
Previously it was documented like so (and WRONG!):
[[<New Idea>|great idea::Recent innovation]]
…as if all the different syntax parts chained. The article now correctly shows the usage where the < > mark-up surrounds the entire input string:
[[<New Idea|great idea::Recent innovation>]]
Hopefully that may help those who are already making heavy use of the new ziplinks feature.
