Link Syntax Question
 

Is there any support for this sort of linking to within an imported HTML file?

(My goal is to write small program to take a folder of interlinked html files, make the appropriate XML from them to be imported, and remake their links into links that work between HTML files inside UR.)

That isn't currently supported, but it's not a bad idea. We'll add it to the request list. Thanks.
