[basex-talk] adding document (as string) to collection

Everyone, Here's my situation: I'm using XQJ. I have an xml document stored as a java string, and I want to store this into an xquery collection. I see no way to do this without using the BaseX-specific libraries. I've looked everywhere, and the only thing I've found that's close is MonetDB's add-doc() function, but that takes a url as an argument, not a string. I want to do something like: insert node $document into collection("test"). Obviously this doesn't work because collections are sequences. Any info is appreciated. -tjw
