Sorry, you're correct. It looks like Xml2Map 1.01 was released after the last B4J version. I guess I must have updated to it manually at some point.
I would presume that it will be included in the next B4J release.
I'm not sure why you'd be averse to downloading the latest version? You'd just be replacing the existing .b4xlib file in the internal libraries folder with the later version.
