No support at WordPress?

I am unable to locate any docs on the web, at WordPress, or at Userland to move the posts I have in OPMLEditor and Radio Userland to this WordPress blog. What happened to “Data Portability”? Big talk years ago from Userland and Dave Winer.

I’ve found plenty of other blogging systems with directions for content exchange. Does anyone have knowledge to share on how I can move my content into WordPress?
