// (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.
