D'ya think this is a backwards compatibility thing because Flash always
used to support invalid XML that had no root node?

This is interesting because it is making explicit something that we've
been doing implicitly.
In LZX we allow a dataset that looks like
<dataset>
<foo/>
<bar/>
<baz/>
</dataset>
Which makes a dataset which looks like
«lz.dataset#0| <foo><foo/><bar/><baz/></foo>»
lzx> foo.childNodes
«Array(3)#1| [<foo/>, <bar/>, <baz/>]»

Because we implicitly make a root node which is never shown.
Many times it is useful to represent list data as XML, and you don't
want to have to force it to have a single root node.
They apparently decided this was common enough to make a class for it.
However, the XMLList object throws and error if
you try to do any XML operations on it, you need to iterate over it's
members if it has length greater than one.
