I confirm I now see interwiki language links
originating from Wikidata
in <language>wiki-<date>-langlinks.sql.gz dumps, with the format
described in the 2nd link you sent. However, this is a MySQL dump, not a
XML dump.
Language links are then no more available in XML data dumps?
I guess not, except – probably – in the XML data dumps for Wikidata
itself, in whatever weird format ContentHandler makes them into.
