[SpecGL Draft] E. Good Practice: Use formal language

This one I'm not sure that it should be included in SpecGL Lite and I 
need more input from the QA WG participants. If you think you can 
develop more ideas and specifically techniques and examples, it means 
it's useful, if not, we will drop it.


Good Practice:
	Use formal language

What does that mean?
	It is possible using formal languages (e.g., XML Schema, UML) to check 
for correctness of the specification and that requirements are 
specified clearly and unambigiously. The checking can be done via 
automated tools.

Why should I care?
	Using a formal language to define a technology means that there is an 
abstract model of your technology and therefore it will be easier to 
develop and write the feature in a consistent manner.
	If the abstract model of the technology doesn't exist, using a formal 
language will help to define it.

Techniques:
	1. Define an abstract model of your technology with a formal language
	2. Use automatic tools to check the consistency of your technology

Examples:

	Examples? For formal language specifications - test the formal 
language. (wiki FormalLanguageVsProse)
