 HTML Methodology

 <p>
 	The following examples show how different data types are represented in HTML.
 	They mirror how the data structures are represented in JSON.
 </p>

 <h5 class='topic'>Simple types</h5>
 <p>
 	The representation for simple types mirror those produced by the XML serializer.
 	Tags are added to help differentiate data types when they cannot be inferred through reflection.
 	These tags are ignored by browsers and treated as plain text.
 </p>
