[Mediawiki-api] About the continue tokens

Hi, All! I found a very strange thing about the continue tokens: The link is here: http://commons.wikimedia.org/w/api.php?action=query&format=xml&revi… I got the following response: <api> <query> <pages> <page pageid="1246719" ns="6" title="File:AB towns+names.png" imagerepository="local" contentmodel="wikitext" touched=" 2012-04-26T19:25:33Z" lastrevid="37692183" counter="" length="447"> <categories> <cl ns="14" title="Category:Locator maps of cities in Alberta"/> <cl ns="14" title="Category:Maps of Alberta"/> <cl ns="14" title="Category:PD-self"/> </categories> <imageinfo> <ii size="82937" width="524" height="700" url=" http://upload.wikimedia.org/wikipedia/commons/1/1d/AB_towns%2Bnames.png&quo… descriptionurl="http://commons.wikimedia.org/wiki/File:AB_towns%2Bname… sha1="0753be62082948bceb1db4205e75d4cf819dbbfa"mime="image/png" bitdepth="8 "/> </imageinfo> <revisions> <rev revid="37692183" parentid="25300971" minor="" user="Qyd" timestamp=" 2010-04-16T02:38:20Z" comment="/* {{int:filedesc}} */ gallery" contentformat ="text/x-wiki" contentmodel="wikitext" xml:space="preserve"> == {{int:filedesc}} == {{Information |Description=Map of [[Alberta]] with cities, towns and roads |Source=GIS data |Date=2006-10 |Author={{User|Qyd}} |Permission=All |other_versions=<gallery> Image:AB-towns-roads.png|without town names Image:AB-towns-highways.png|simplified Image:AB-cities-roads.png|cities and highways </gallery> }} [[Category:Maps of Alberta]] [[Category:Locator maps of cities in Alberta|*]] == {{int:license}} == {{PD-self}} </rev> </revisions> </page> </pages> </query> <limits categories="500"/> <continue continue="||categories|info|revisions" iistart=" 2006-10-05T10:33:30Z"/> </api> I found there was a continue token at the end of the response, Then I use: http://commons.wikimedia.org/w/api.php?action=query&format=xml&revi… to get the following response: <api> <limits categories="500"/> <query> <pages> <page pageid="1246719" ns="6" title="File:AB towns+names.png" imagerepository="local"> <imageinfo> <ii size="76966" width="524" height="700"url=" http://upload.wikimedia.org/wikipedia/commons/archive/1/1d/20061006020043%2… "descriptionurl="http://commons.wikimedia.org/wiki/File:AB_towns%2Bnames.png " sha1="387284aaeea43dfae091e965e19cc47ce99dcf49"mime="image/png" bitdepth=" 8"/> </imageinfo> </page> </pages> </query> <continue continue="||categories|info|revisions" iistart=" 2006-10-04T23:32:38Z"/> </api> I found in the response we didn't have the revisions information any more. I think this may be a bug? Because I found if we set clcontinue to request the following page, the response will not miss the revisions information. P.S. Another question: Are the items in imageinfo list sorted by timestamp? I mean from latest to oldest. Thanks.
