The XML that I use to create nodes may get updated once in a while.
The property that I use has a "changed" attribute that I import into the "changed" property of the node. If I replace the old XML file by a new one, I would like that migrate checks the "changed" property in the XML file and compares it with the one in the database. If the XML one is more recent, the node should be marked as "needs an update".
Is this feasible?
