-This is a more detailed description of the actual changes desired.  The contents of this section will vary based on the target of the RFC, be it a technical change, website change, or process change.  For example, for a technical change, items such as files, XML schema changes, and API chances would be identified.  For a process change, the new process would be laid out in detail.  For a website change, the files affected would be listed.

 An additioanl OEM component has been added to the source -- jsoncpp. Jsoncpp is a C++ implementation of the JSON specification (http://sourceforge.net/projects/jsoncpp/).
 
 Two additional classes have been added to assist the JSON implementation in !MapGuide:
+
 1) The !MgJsonDoc Class
+
 - !MgJsonDoc is a wrapper over the jsoncpp implementation. !MgJsonDoc provides many easy-to-use interfaces, such as Begin* and End*, for creating JSON documents from an XML perspective. For example, to create as JSON document for the corresponding XML content---<Node>Text</Node>---, one would call !BeginObject("Node"), !SetValue("Text"), and !EndObject() subsequently.
 
-2) The MgXmlJsonConvert Class
+2) The !MgXmlJsonConvert Class
+
 - !MgXmlJsonConvert converts an XML document into a JSON formatted document.

 where the appended labeling scheme indicates the different implementation considerations:
+
 (1) Web-tier changes -- every !ToXml function is matched with an !ToJson function implementation that creates a JSON document in place,
+
 (2) Web-tier changes -- utilizes the !MgXmlJsonConvert class to convert XML documents to JSON documents.
+
 (3) Server changes -- an extra parameter "CREFSTRING format" has been added to the respective API call; the !MgXmlJsonConvert class is used if format equals to the JSON MIME type.
+
 (4) Server changes -- an extra API has been added matching the respective API call (e.g. !DescribeSchemaAsXml has !DescribeSchemaAsJson as the JSON version, and !GetFDOCacheInfo has !GetFDOCacheInfoAsJson as its JSON specific implementation); this is because the original APIs return "STRING" and could not be efficiently adapted by the conversion process within the !MgXmlJsonConvert class implementation; and for the affected APIs, the !MgByteReader* is returned instead.
