Techniques 4.5 GP A

one should keep in mind that extensibility may need new syntax tokens 
([WEB-ARCH], extensibility), which can be smoothen by the use of two 
policies:
	 * "must†Understand": This mechanism is required when the data are 
critical for the technology, or when their lost would result in major 
flaws.
	 * "must†Ignore": This mechanism will be used when the processing of 
data would create a major flaw in the application. Then it becomes safe 
to ignore them altogether.
