Yes, that is how it currently works.  Note if you do this:

node1 = XML::Node.new('foo')
node1 << '<bar/>'

You get this:

<foo>&lt;bar/&gt;</foo>

Which seems fine to me.

However, that doesn't really help with this issue:

node = XML::Node.new('foo') << XML::Node.new('bar') << XML::Node.new('baz')

If << returns self, then you get:

'<foo><bar/><baz/></foo>' where node points to foo

If << returns the appended child, then:

'<foo><bar><baz/></bar></foo>' where node points to baz.  Its the 
pointing to baz bit I don't like.
