Re: Pattern: Static Properties Return Objects

I tend to the side of inheritance simply because your requirements may
change and DetailLines may need some new functionality or new feature that
HeaderLines does not or vise versa.  It makes sense then to now, even if
it's nothing more than an empty class declaration, create those classes and
utilize a DetailLines and HeaderLines instead of a LineList so that lots of
time needs to be spent later refactoring your code.  If you don't foresee
that or think it would happen then I see no reason to do so.
