  Transforms an XML element into a JSON string representation.  See http://json.org.
 | 
						|
  <p/>
 | 
						|
  Sample usage:
 | 
						|
  <pre>
 | 
						|
    xquery version "1.0-ml";
 | 
						|
    import module namespace json="http://marklogic.com/json" at "json.xqy";
 | 
						|
    json:serialize(&lt;foo&gt;&lt;bar&gt;kid&lt;/bar&gt;&lt;/foo&gt;)
 | 
						|
  </pre>
 | 
						|
  Sample transformations:
 | 
						|
  <pre>
 | 
						|
  &lt;e/&gt; becomes {"e":null}
 | 
						|
  &lt;e&gt;text&lt;/e&gt; becomes {"e":"text"}
 | 
						|
  &lt;e&gt;quote " escaping&lt;/e&gt; becomes {"e":"quote \" escaping"}
 | 
						|
  &lt;e&gt;backslash \ escaping&lt;/e&gt; becomes {"e":"backslash \\ escaping"}
 | 
						|
  &lt;e&gt;&lt;a&gt;text1&lt;/a&gt;&lt;b&gt;text2&lt;/b&gt;&lt;/e&gt; becomes {"e":{"a":"text1","b":"text2"}}
 | 
						|
  &lt;e&gt;&lt;a&gt;text1&lt;/a&gt;&lt;a&gt;text2&lt;/a&gt;&lt;/e&gt; becomes {"e":{"a":["text1","text2"]}}
 | 
						|
  &lt;e&gt;&lt;a array="true"&gt;text1&lt;/a&gt;&lt;/e&gt; becomes {"e":{"a":["text1"]}}
 | 
						|
  &lt;e&gt;&lt;a type="boolean"&gt;false&lt;/a&gt;&lt;/e&gt; becomes {"e":{"a":false}}
 | 
						|
  &lt;e&gt;&lt;a type="number"&gt;123.5&lt;/a&gt;&lt;/e&gt; becomes {"e":{"a":123.5}}
 | 
						|
  &lt;e quote="true"&gt;&lt;div attrib="value"/&gt;&lt;/e&gt; becomes {"e":"&lt;div attrib=\"value\"/&gt;"}
 | 
						|
  </pre>
 | 
						|
  <p/>
 | 
						|
  Namespace URIs are ignored.  Namespace prefixes are included in the JSON name.
 | 
						|
  <p/>
 | 
						|
  Attributes are ignored, except for the special attribute @array="true" that
 | 
						|
  indicates the JSON serialization should write the node, even if single, as an
 | 
						|
  array, and the attribute @type that can be set to "boolean" or "number" to
 | 
						|
  dictate the value should be written as that type (unquoted).  There's also
 | 
						|
  an @quote attribute that when set to true writes the inner content as text
 | 
						|
  rather than as structured JSON, useful for sending some XHTML over the
 | 
						|
  wire.
 | 
						|
  <p/>
 | 
						|
  Text nodes within mixed content are ignored.
 | 
						|
 | 
						|
  @param $x Element node to convert
 | 
						|
  @return String holding JSON serialized representation of $x
