Jeff Gothelf Throws out this snippet in his article on boxes and arrows

Proponents of HTML wireframes believe that, if developed according to company standards, the HTML can be reused to build the actual site. This would require the IA to have expert coding skills that take advantage of the latest developments and trends in coding such as XML, XHTML, and CSS. However, by building a high-fidelity prototype that is meant to be the codebase for the actual application, the IA has less room to experiment with various architectures and ideas as changes could alter code marked for reuse. Again, the “screen notes” section could not be implemented as it would not be part of the final application. This would relegate any supporting documentation to an external document which would then need to be compared with the prototype.

It’s a great testament to providing a way for IA’s to do what they do best, but not leave their work as an artifact. Pre-project work should turn into the project at some point.
