BaseX 6.5.1 *still* has issues with producing illegal XML. See http://top.cs.vt.edu/~gback/bx/b651-bug/ for a snapshot of the BaseXData directory with instructions on how to reproduce it. BaseX returns: <entry xmlns="http://libx.org/xml/libx2" xmlns="http://www.w3.org/2005/Atom"> which obviously is invalid XML. - Godmar
