One of the arguments there is that it is difficult to tell users what to
do when faced with the problem of ill-formed documents. I am curious, is
there any service that would help me to ensure the well-formedness or
even the validity of my documents, something I can tell what my docs are
and how to contact me in case an error is encountered so I can take care
of it?

I am not sure whether it would apply to the Atom format, but for HTML/
XHTML documents it seems difficult to stay valid after it is once
achieved, at least the amount of web sites that have a "Valid Foo" badge
and a link to the W3C MarkUp Validator that are actually invalid seems
to suggest that. I think the easier to use tools that help to conform
the more will. And I think a tool that regularly checks documents would
be a great help and would thus mitigate the risk that implementers have
to deal with ill-formed content.
