+  #
+  # == Notes:
+  #
+  # * The order that attributes are inserted in markup tags is
+  #   undefined. 
+  #
+  # * Sometimes you wish to insert text without enclosing tags.  Use
+  #   the <tt>text!</tt> method to accomplish this.
+  #
+  #   Example:
+  #
+  #     xm.div {                          # <div>
+  #       xm.text! "line"; xm.br          #   line<br/>
+  #       xm.text! "another line"; xmbr   #    another line<br/>
+  #     }                                 # </div>
+  #
+  # * The special XML characters <, >, and & are converted to &lt;,
+  #   &gt; and &amp; automatically.  Use the <tt><<</tt> operation to
+  #   insert text without modification.
+  #
+  # * Sometimes tags use special characters not allowed in ruby
+  #   identifiers.  Use the <tt>tag!</tt> method to handle these
+  #   cases.
+  #
+  #   Example:
+  #
+  #     xml.tag!("SOAP:Envelope") { ... }
+  #
+  #   will produce ...
+  #
+  #     <SOAP:Envelope> ... </SOAP:Envelope>"
+  #
+  #   <tt>tag!</tt> will also take text and attribute arguments (after
+  #   the tag name) like normal markup methods.  (But see the next
+  #   bullet item for a better way to handle XML namespaces).
+  #   
+  # * Direct support for XML namespaces is now available.  If the
+  #   first argument to a tag call is a symbol, it will be joined to
+  #   the tag to produce a namespace:tag combination.  It is easier to
+  #   show this than describe it.
+  #
+  #     xml.SOAP :Envelope do ... end
+  #
+  #   Just put a space before the colon in a namespace to produce the
+  #   right form for builder (e.g. "<tt>SOAP:Envelope</tt>" =>
+  #   "<tt>xml.SOAP :Envelope</tt>")
+  #
+  # * XmlMarkup builds the markup in any object (called a _target_)
+  #   that accepts the <tt><<</tt> method.  If no target is given,
+  #   then XmlMarkup defaults to a string target.
+  # 
+  #   Examples:
+  #
+  #     xm = Builder::XmlMarkup.new
+  #     result = xm.title("yada")
+  #     # result is a string containing the markup.
+  #
+  #     buffer = ""
+  #     xm = Builder::XmlMarkup.new(buffer)
+  #     # The markup is appended to buffer (using <<)
+  #
+  #     xm = Builder::XmlMarkup.new(STDOUT)
+  #     # The markup is written to STDOUT (using <<)
+  #
+  #     xm = Builder::XmlMarkup.new
+  #     x2 = Builder::XmlMarkup.new(:target=>xm)
+  #     # Markup written to +x2+ will be send to +xm+.
+  #   
+  # * Indentation is enabled by providing the number of spaces to
+  #   indent for each level as a second argument to XmlBuilder.new.
+  #   Initial indentation may be specified using a third parameter.
+  #
+  #   Example:
+  #
+  #     xm = Builder.new(:ident=>2)
+  #     # xm will produce nicely formatted and indented XML.
+  #  
+  #     xm = Builder.new(:indent=>2, :margin=>4)
+  #     # xm will produce nicely formatted and indented XML with 2
+  #     # spaces per indent and an over all indentation level of 4.
+  #
+  #     builder = Builder::XmlMarkup.new(:target=>$stdout, :indent=>2)
+  #     builder.name { |b| b.first("Jim"); b.last("Weirich) }
+  #     # prints:
+  #     #     <name>
+  #     #       <first>Jim</first>
+  #     #       <last>Weirich</last>
+  #     #     </name>
+  #
+  # * The instance_eval implementation which forces self to refer to
+  #   the message receiver as self is now obsolete.  We now use normal
+  #   block calls to execute the markup block.  This means that all
+  #   markup methods must now be explicitly send to the xml builder.
+  #   For instance, instead of
+  #
+  #      xml.div { strong("text") }
+  #
+  #   you need to write:
+  #
+  #      xml.div { xml.strong("text") }
+  #
+  #   Although more verbose, the subtle change in semantics within the
+  #   block was found to be prone to error.  To make this change a
+  #   little less cumbersome, the markup block now gets the markup
+  #   object sent as an argument, allowing you to use a shorter alias
+  #   within the block.
+  #
+  #   For example:
+  #
+  #     xml_builder = Builder::XmlMarkup.new
+  #     xml_builder.div { |xml|
+  #       xml.stong("text")
+  #     }
+  #
+  class XmlMarkup < XmlBase
+
+    # Create an XML markup builder.  Parameters are specified by an
+    # option hash.
+    #
+    # :target=><em>target_object</em>::
+    #    Object receiving the markup.  +out+ must respond to the
+    #    <tt><<</tt> operator.  The default is a plain string target.
+    #    
+    # :indent=><em>indentation</em>::
+    #    Number of spaces used for indentation.  The default is no
+    #    indentation and no line breaks.
+    #    
+    # :margin=><em>initial_indentation_level</em>::
+    #    Amount of initial indentation (specified in levels, not
+    #    spaces).
+    #    
+    # :escape_attrs=><b>OBSOLETE</em>::
+    #    The :escape_attrs option is no longer supported by builder
+    #    (and will be quietly ignored).  String attribute values are
+    #    now automatically escaped.  If you need unescaped attribute
+    #    values (perhaps you are using entities in the attribute
+    #    values), then give the value as a Symbol.  This allows much
