Some issues here: * Is the inheritance down a collection hierarchy (from a collection to its members), or up a hierarchy (from a member to its parents), or does there need to be a mechanism for specifying the inheritance pattern? * Which takes precedence, the inheritance operation, or a lock? That is, if A inherits properties from B, and A is locked, what is the effect of a PROPPATCH on B? Does it succeed, or does it fail, due to the lock on A? > Indeed, what is preparationed in Webdav if a resource has a property > with more than one value.

We left this up to the definition for each individual property. There are many ways to represent this. For example: <authors> <author>...</author> <author>...</author> ... </authors> or <author> <elem1>...</elem1> <elem2>...</elem2> ... </author> or <author> <list> <li>...</li> <li>...</li> ... </list> </author> - Jim
