Section, Heading and list of parameter
Comments: Something very important and different from other languages and tools, Any line written apart from valid headings or do not contains character (=) are comments.
Null Values: Here is the deal Parameter can be assigned by NULL values.
Spaces: Something very important, **Remember** Integration service will consider space as part of value assigned to it, if there is a space between parameter name and equal sign. This can create big time issue sometime, I have faced it few times:-).
