In the IBM Connections user interface, it's possible to attach files directly to wiki pages.  

I want to attach files to wiki pages programatically, but can't find a documented way to do so.

I've been looking at the Connections 4.5 API documentation here:  

<http://www-10.lotus.com/ldd/appdevwiki.nsf/xpDocViewer.xsp?lookupName=IBM+Connections+4.5+API+Documentation#action=openDocument&content=catcontent&ct=prodDoc>

Looking specifically at the APIs for Files and Wikis, there seems to be nothing about wiki-page attachments. While I'm mainly looking to upload attachments, I can't even see a documented API to retrieve attachments, despite the user-interface having a link to a feed (on each wiki page) that does that.

Is there any (possibly undocumented) API to attach files to a wiki page?
