/**
 * 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.
