I just want to say that I agree with Geoff on his message. The statement that I have extracted above conveys my sentiment. In particular, getting the design right is hard with the Web because the collection and evolution aspect of the Web is made tricky because of - the type of collections that web sites are - the type of property support needed for web collections - the type of collaboration needed in authoring webs This is why I liked Geoff's design that he circulated a while ago. It provides for minimal needed functionality and yet addresses future extensibility. It draws the design "line in the sand" at the right place and in the right way The discussion that preceded this message about collections with references, mutable properties, one method for lock and versioning all point to the difficulty of getting this right.
