148  Transforms an XML element into a JSON string representation.  See http://json.org.
149  &lt;p/&gt;
150  Sample usage:
151  &lt;pre&gt;
152    xquery version &quot;1.0-ml&quot;;
153    import module namespace json=&quot;http://marklogic.com/json&quot; at &quot;json.xqy&quot;;
154    json:serialize(&amp;lt;foo&amp;gt;&amp;lt;bar&amp;gt;kid&amp;lt;/bar&amp;gt;&amp;lt;/foo&amp;gt;)
155  &lt;/pre&gt;
156  Sample transformations:
157  &lt;pre&gt;
158  &amp;lt;e/&amp;gt; becomes {&quot;e&quot;:null}
159  &amp;lt;e&amp;gt;text&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:&quot;text&quot;}
160  &amp;lt;e&amp;gt;quote &quot; escaping&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:&quot;quote \&quot; escaping&quot;}
161  &amp;lt;e&amp;gt;backslash \ escaping&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:&quot;backslash \\ escaping&quot;}
162  &amp;lt;e&amp;gt;&amp;lt;a&amp;gt;text1&amp;lt;/a&amp;gt;&amp;lt;b&amp;gt;text2&amp;lt;/b&amp;gt;&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:{&quot;a&quot;:&quot;text1&quot;,&quot;b&quot;:&quot;text2&quot;}}
163  &amp;lt;e&amp;gt;&amp;lt;a&amp;gt;text1&amp;lt;/a&amp;gt;&amp;lt;a&amp;gt;text2&amp;lt;/a&amp;gt;&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:{&quot;a&quot;:[&quot;text1&quot;,&quot;text2&quot;]}}
164  &amp;lt;e&amp;gt;&amp;lt;a array=&quot;true&quot;&amp;gt;text1&amp;lt;/a&amp;gt;&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:{&quot;a&quot;:[&quot;text1&quot;]}}
165  &amp;lt;e&amp;gt;&amp;lt;a type=&quot;boolean&quot;&amp;gt;false&amp;lt;/a&amp;gt;&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:{&quot;a&quot;:false}}
166  &amp;lt;e&amp;gt;&amp;lt;a type=&quot;number&quot;&amp;gt;123.5&amp;lt;/a&amp;gt;&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:{&quot;a&quot;:123.5}}
167  &amp;lt;e quote=&quot;true&quot;&amp;gt;&amp;lt;div attrib=&quot;value&quot;/&amp;gt;&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:&quot;&amp;lt;div attrib=\&quot;value\&quot;/&amp;gt;&quot;}
168  &lt;/pre&gt;
169  &lt;p/&gt;
170  Namespace URIs are ignored.  Namespace prefixes are included in the JSON name.
171  &lt;p/&gt;
172  Attributes are ignored, except for the special attribute @array=&quot;true&quot; that
173  indicates the JSON serialization should write the node, even if single, as an
174  array, and the attribute @type that can be set to &quot;boolean&quot; or &quot;number&quot; to
175  dictate the value should be written as that type (unquoted).  There's also
176  an @quote attribute that when set to true writes the inner content as text
177  rather than as structured JSON, useful for sending some XHTML over the
178  wire.
179  &lt;p/&gt;
180  Text nodes within mixed content are ignored.
181
182  @param $x Element node to convert
183  @return String holding JSON serialized representation of $x
