I'm no expert on this field (XQuery), but AFAIK there is no such thing like "XQuery document": XQuery is an expression and functional language, who evaluate expressions. For example:
3 + 5
Is a full XQuery expression that an XQuery parser can evaluate. In fact, a "XQuery document" is a XQuery expression that may consist of other expressions.
A XQuery expression may evaluate to an XML document (well-formed of course), but still, it can evaluate just to a chunk of bytes (string)...
Anyway, your point of view is very interesting.

So, you might conclude, "A fundamental rule in XML is that the "<" symbol
is reserved and must be escaped. XQuery does not heed this rule.
Therefore, an XQuery document is not an XML document."
Okay, I give up. Which is it? XML or not? If it's not XML then why
is it called "XML Query Language"? /Roger
