Generic XML data that stores all unknown key name/value pairs.
Each data key name maps into the name of the XPath expression value for the XML element,
attribute, or text content (using
"text()"). Subclasses can declare fields for known XML
content using the
Key annotation. Each field can be of any visibility (private, package
private, protected, or public) and must not be static.
null unknown data key names are
not allowed, but
null data values are allowed.
Implementation is not thread-safe. For a thread-safe choice instead use an implementation of
ConcurrentMap.
