No. See

2.4.2/fpc/packages/fcl-xml/src/dom.pp

function CompareDOMStrings(const s1, s2: DOMPChar; l1, l2: integer):
integer;
var i: integer;
begin
  Result:=l1-l2;
  i:=0;
  while (i<l1) and (Result=0) do begin
    Result:=ord(s1[i])-ord(s2[i]);
    inc(i);
  end;
end;

No. laz_xmlwrite and laz2_xmlwrite use laz_dom, laz2_dom.
