[xquery-talk] Update bug?

Try reversing the order of your statements, first inserting the node as a
child of <b/> before deleting it.
Also, you probably don't want to be using // in your selectors, which means
the descendant-or-self axis. With that XPath expression, any @att at any
level of the document would be copied and then deleted. Instead, use exact
paths with a single /, which is the child axis.
insert node doc("xml.xml")/a/@att into doc("xml.xml")/a/b,
delete node doc("xml.xml")/a/@att
