Let's look at the specification of XML, https://www.w3.org/TR/REC-xml/ We see in section 2.1, [[ [Definition: A textual object is a well-formed XML document if:] Taken as a whole, it matches the production labeled document. It meets all the well-formedness constraints given in this specification. Each of the parsed entities which is referenced directly or indirectly within the document is well-formed. ]] So we need our input to match Document. The immediately following text in the spec has, [[ Document [1] document ::= prolog element Misc* ]] If you follow these you find "element" means we need exactly one top- level element, <foo>...</foo>, and your example has a comment but no element. So, it is not well-formed. You will find it helpful to become moer familiar with the grammar in the XML specification.
