This package contains classes used internally by the PracticalXML library. Applications should not rely on the API of these classes, or indeed of their continued existence. In most cases, there's a better alternative in a third- party library.

A note on naming: externally-facing utility classes end with "Util", while internal classes end with "Utils" (note the "s"). Examples: `DomUtil` is meant for external use, while `StringUtils` is internal.
