Maybe, but we could not think of any, and no one has suggested any yet. Do you have an example that we should deal with? >To be complete, 'typical' ,'cannot .. exactly' and 'in general' had >better be removed and >the classification should first define "strored strings" precisely and then >define the complement set as the "queries" if it is proved that >any 3rd type does not exist. That would indeed be complete. It is also impossible to do for the hundreds (thousands?) of Internet protocols. >I have doubt that there are many *gray areas* that do not fall into >either categories. Your doubt may be correct, but we cannot act on your doubt without some concrete examples. --Paul Hoffman, Director --Internet Mail Consortium
