Re: xml-sax issue

["RPG List" <rpglist@xxxxxxxxxxx>]

one additional issue I saw this morning Scott and maybe this is the
problem, the incoming XML does not have what I would call a standard
header:

IE: it does not have a version or description that I see in most xml
documents, maybe that's needed or maybe not?
