|This rule is Obsolete|
|Synopsis:||Once a default parameter value is defined, the value may never be changed|
Once a parameter has been declared with a default value, this value may never be changed. Reason is that code calling the method relies on this default value and probably will break when the default value changes. For example, the code:
Reset(int start = 0);
should not be changed later to:
Reset(int start = 1);
An acceptable alternative would be to fix all callers.
