I tried=20
\directlua{lxml.registerentity("DATE","NEWDATE")}
and
\directlua{lxml.registerentity("DATE","NEWDATE")}

but neither does effect a change in the entity.

Why is that entry not set in the Lua-table entities? (file xml-ent.lua) =
has as that function:

function xml.registerentity(key,value)
    entities[key] =3D value
    if trace_entities then
        report_xml("registering entity %a as %a",key,value)
    end
end
