ASP.NET Literal WebControl: Why Use PassThrough Mode?

For an ASP.NE开发者_如何学编程T Literal control, is there ever any reason to use LiteralMode.PassThrough instead of the default, LiteralMode.Transform?

I've never seen any cases where this makes sense, but I suppose it's there for those situations where you want fine-grained control over the transform.

I've used the PassThrough mode two times when I was putting HTML into the Literal control's Text property and did not want the HTML to be altered. I cannot remember the exact details, but the Transform mode was not suitable because it allowed some unwanted alterations to the HTML.
