+// Thread safe class for representing XML data as a structured object. This
+// class should not be used with large XML documents because all data will be
+// resident in memory at the same time. This implementation supports a
+// restricted set of XML features:
+// <pre>
+// (1) Processing instructions, whitespace and comments are ignored.
+// (2) Elements and attributes must always be referenced using the fully
+// qualified name (ie, namespace:localname).
+// (3) Empty elements (<a/>) and elements with zero-length values (<a></a>)
+// are considered the same.
+// (4) Element nodes are considered part of a value if:
+// (a) The element node follows a non-element node at the same depth
+// (see 5), or
+// (b) The element node does not have a namespace and the parent node does.
+// (5) Mixed node types at the same depth are combined into a single element
+// value as follows:
+// (a) All node values are concatenated to form a single string value.
+// (b) Entity reference nodes are resolved to the corresponding entity
+// value.
+// (c) Element nodes are represented by their outer XML string.
+// </pre>
