/**
* Interface that defines API for the factories stream writers use for
* creating "escaping writers". These factories are used when defining
* custom escaping of text (as well as possibly used by the
* implementations for default escaping too). Escaping in this context
* refers to the process of replacing individual text/attribute content
* character with pre-defined and character entities, as per XML
* specification (2.4, Appendix D).
*
* Typical escaping writers replace characters like '<' and '&',
* as well as some additional characters depending on context.
* Custom implementations may choose to escape additional characters,
* for example to make it easier to manually view or edit resulting
* serialized XML document.
*
* Note about implementing escaping writers: writers need to obey normal
* Writer semantics, and specifically they should pass calls to
* flush() and close() to the underlying
* Writer.
