This same type of issue came up with meta data. I believe the decision we made then applies here. If it isn't critical to implementing the DAV spec, then it shouldn't be in the spec. How is providing a structure for HTML, critical to implementing the DAV spec? Also, why would anyone even write a structure for HTML? It was never designed to be interpreted in that way. Now, if you would like to have a spec on how OLE compound files, MHTML files, e-mail files, etc. have structure, it will be easy to accommodate you. As for legacy, I don't understand the issue. If a piece of software is faulty, it is faulty. A server should not expose a structure on a resource it can not properly interpret. Using Jim's example, the product Jim used should not have accepted a file it could not understand.
