I very much agree with Jirka and want to add that there are two aspects of
provenance. One is what Maxime described. The other is a provenance
description of content items. E.g. something like
<span its-provref="someURI">some translated text</span>
in this example someURI points to a provenance description. ISSUE-22 is
about whether we should go that route. Here the work of the provenance
working group might be relevant for us.
