The escape mark-up is used when we don't want to do any processing.

'''
escape (no processing/formatting)
'''

Escaping allows us to pass XML markup to BoostBook or DocBook. For example:

'''
<emphasis role="bold">This is direct XML markup</emphasis>
'''

This is direct XML markup

	Important
	Be careful when using the escape. The text must conform to BoostBook/DocBook syntax.
