handrawn, yes it works backwards, probably from v19.1 (I have v18).
What you will see is an Information block to advise newer components have been detected and so these might not be editable in earlier versions.
I have found some Xara versions do not recognise the WIX and bomb, so it is probably very fragile so do try against your setup before committing to it fully.

As shown, Xara cannot be relied on to keep functionality current so building in you own metadata mechanism has to be safest.

@Xara
A WIX file stores all its past saves - that alone is extremely useful to a designer.
Moreover, you have also decided not longer implement the Windows Registry setting for Document Information, so what was once useful History is hidden but awkwardly accessible through a WIX, which you have also fudged away.

This is what we've lost.

The L() number is the seconds number value that you can use to convert to date since timestamp or unix epoch.
Input the number to show the datetime - https://www.epochconverter.io.

The decode of most of the other data is fairly human-readable.
