Hi Hans,
more serious: today's beta doesn't process my xml files. Too late today 
for a minimal example; maybe the error can give a clue:
systems         : end file vorlesung-mkiv at line 1
systems         : begin file historiker at line 1
! LuaTeX error no string to print

Thank goodness I still have an older version around...
in lxml-ent.lua ...

function xml.resolved_entity(str)
     local e = xml.entities[str]
     if e then
         local te = type(e)
         if te == "function" then
             e(str)
         elseif e then
             texsprint(ctxcatcodes,e)
         end
     else
         texsprint(ctxcatcodes,"\\xmle{",str,"}{",utfupper(str),"}") -- 
we need to use our own upper
     end
end

there has been quite some changes in the xml machinery; what exactly do 
you do with entities?
