JavaScript: test that new XML copies a list item's attributes and children

Browse Source 
The test for new XML with a one-item list now starts from an item that
has a parent, an attribute and a child. It checks that the copy has no
parent and that changing the copy's attribute and child leaves the
original unchanged, so a copy that drops or shares the children fails.
