How can I retrieve the version of the template upon which current document is based?
I thought of using File>Properties to store a version number in a custom property. Unfortunately, properties, like initial contents, are not “monitored” once the .odt document is created.
This behaviour is part of the game: forwarding modified template initial contents could delete data in the real document because this initial contents could have been edited. Similarly, properties may have been changed for document purpose and forcing them to new template values would result in data loss.
The question is: which trick could I use in the template so that some value can be retrieved to be inserted (as a field?) to echo the template value in the document and have this field follow changes in the template?
