+<html>
+<body>
+
+This package contains classes to convert JSON (JavaScript Object Notation)
+strings (as defined <a href="http://www.json.org/">json.org</a> ) to and
+from an XML DOM. Although both XML and JSON are textual representations of
+hierarchical data, there are some peculiarities in the conversion:
+
+<dl>
+<dt> Container Element
+<dd> Although elements within a JSON object are named, the object itself is
+ not. XML requires a named root element, so the JSON->XML conversion
+ creates a root element named "data", and the XML->JSON conversion ignores
+ the passed root element.
+<dt> Document Order
+<dd> In XML, document order is important and may be validated; in JSON, the
+ order of elements within an object is not important. To support arrays
+ (qv), the XML->JSON conversion intentionally breaks document order. And
+ as JSON has no intrinsic order, you'll need to explicitly re-arrange the
+ result of a JSON->XML conversion prior to any validation.
+<dt> Non-String Data
+<dd> JSON supports numbers and boolean literals in addition to quote-delimited
+ strings. The JSON->XML conversion will handle these values transparently.
+ The default XML->JSON conversion writes all content as quote-delimited
+ strings, but there is a conversion option to recognize a limited set of
+ non-string elements based on the <code>xsi:type</code> attribute.
+<dt> Arrays
+<dd> XML does not have a defined array construct, but may repeat elements; JSON
+ has a defined array construct, and repeated elements will overwrite the
+ former definition. To avoid this problem, the XML->JSON conversion will
+ identify all repeated elements and create an array construct. The default
+ JSON->XML conversion creates a parent-children construct (which is more
+ palatable to subsequent XML->Java conversion), but a conversion option
+ allows conversion to a repeated element.
