Strictly speaking it isn't, because the output is a sequence of items
and therefore not always a single document, and the notion of
well-formedness is only defined for full documents. But apart from that
all fragments in the result always satisfy the requirements for
well-formedness for fragments in documents. This is so because they will
always belong to the XPath/XQuery data model, which doesn't allow
anything that isn't well-formed by definition. You can check the W3C
documents if you don't believe me. :-)
