I noticed that the response from "http://www.wikidata.org/w/api.php?action=query&titles=Q1&prop=revisions&rvprop=content&format=xml" changed from "entity":"q1" to "entity":["item",1].

Is this change applied to all pages?

In the latest wikidata dump (http://dumps.wikimedia.org/wikidatawiki/latest/wikidatawiki-latest-pages-meta-current.xml.bz2), both formats exist at the same time. For example, page Q100 has: "entity":["item",100], while page Q100000 has "entity":"q100000". Is it expected? Will the next dump have same format?

By the way, "http://www.wikidata.org/w/api.php?action=query&titles=Q100000&prop=revisions&rvprop=content&format=xml" return "entity":["item",100000].
