Technically, a 4741 server can contain a string. That does not mean we have to allow that in 4741bis, now that we are using YANG instead of continuing with an ad-hoc opaque content layer. Since the 'single-string' <config> is completely incompatible with YANG modules, there is no role for such a server implementation in the standard. But we can remove the description-stmt text in question, and be silent on this issue. It is a market decision whether or not a vendor wants to sell a NETCONF server that can never implement a YANG module. > > /martin > > Andy
