All valid documents must be well-formed; or, in other words, anything
allowed in a valid document is by definition allowed in a well-formed
document (or else the valid document would fail to be well-formed).
Well-formedness is simply a lower level of syntactic checking for a
document; it is not a restricted subset of XML.

I am not certain that I really understand the question.
