Rails - Aug 2009 - XML tags being converted to lowercase

I have the following method to deliver an xml response:

  def xslt_layout
    @ticket = Ticket.find_by_id(params[:id])
    render :text => "#{@ticket.xml}", :layout => false,
:filename => "#
{@ticket.ticket_number}.xml", :content_type =>
"application/xml"
  end

The xml is generated using Builder as a Ticket model method and has
both camel case and upper case element names in it.
Inspecting the xml using a script/console query shows the tag names in
the correct case, but the Rails stack is converting them to lowercase
e.g. <Ticket/> becomes <ticket/>

How can I prevent this behaviour?

Problem solved - it''s the Safari DOM inspector that''s doing
it.
