The name of the processing instruction that is sent if the result tree disables output escaping.

  The name of the processing instruction that is sent if the result tree disables output escaping.

Normally, result tree serialization escapes & and < (and possibly other characters) when outputting text nodes. This ensures that the output is well-formed XML. However, it is sometimes convenient to be able to produce output that is almost, but not quite well-formed XML; for example, the output may include ill-formed sections that will be transformed into well-formed XML by a subsequent non-XML aware process. If a processing instruction is sent with this name, serialization should be output without any escaping.

Result DOM trees may also have PI_DISABLE_OUTPUT_ESCAPING and PI_ENABLE_OUTPUT_ESCAPING inserted into the tree.
