RE:  Error and Fatal Error
As the originator is a .NET programmer

String nodeValue = System.Security.SecurityElement.Escape(inputValue)

Should handle all his input problems....

There are other similar methods such as HtmlEncode, catching an XmlWriter
stream, or even serial substitutions in a single overloaded line.

If you're going to get legalese about it, then:

(a) XML is a language defined in a specification.

(b) A document is not a language, so a document is never XML; nor can "an
XML" contain illegal characters, nor can "the XML" contain errors.

(c) The XML language specification defines what it means for a piece of text
to be a "well-formed XML document". It's a slightly unfortunate term,
because it's easy to imagine that it implies the existence of XML documents
that are not well-formed. But that would be a misreading of the spec: no
such category exists.

(d) The specification never talks about "errors in the XML". That would be a
contradiction in terms. The specification in fact doesn't give a name to the
thing that has errors, though it would be reasonable to talk about "errors
in the input to the XML processor".
