Implementation of specifications will usually throw up problems and it almost never happens that a protocol specification is defined so jesuitically that ambiguity doesn't happen. Looking at this from another angle, engineering is about optimisation of conflicting input parameters. The IETF needs to understand how and why this happens, because it can provide useful feedback on the rfcs that are churned out, ranging from ambiguity to gap analysis to impracticality. Nick
