Why does this XmlMarkup return blank?

Both of these methods are in the controller. The method is called with /<controller plural>.xml;directory. The route completes, I get

XML Parsing Error: no element found Location: <controller plural>.xml;mytest Line Number 1, Column 1:

def mytest

    respond_to do |format|       format.html # index.rhtml       format.xml { render :xml => try_xml_builder }     end   end

def try_xml_builder

    xml = Builder::XmlMarkup.new(:indent=>2)     xml.instruct!     xml.person { |b| b.name("Jim"); b.phone("555-1234") }     return xml   end

If I override to_xml with the same builder script in the mode, everything is great. There's something wrong with the xml return value and render :xml, but I'm not sure what it is. The example for builder is from the builder pages, and returns the correct xml.

I'm running rails 1.2.2.
