Remarks

Any class specified in an inherits directive must match this class in a duck-typing style.

Note that this class therefore specifies an implicit contract with the transformation object. The object doesn't have to derive from any specific type or interface, but it must have a) A void Initialize() method. b) A string TransformText() method c) An Errors property that's duck-compatible with CompilerErrorCollection d) A GeneratonEnvironment property that's duck-compatible with StringBuilder. e) A void Write(string) method

Using any further features of T4 such as expression blocks will require the class to have further methods, such as ToStringHelper, but those will produce regular compiler errors at transform time that the base class author can address.

These few methods together form a subset of the TextTransformation default base class' API.

If you change this pseudo-contract to add more requirements, you should consider this a breaking change. It's OK, however, to change the contract to have fewer requirements.
