Yup. Sometimes clumsiness in syntax can be a correct disincentive:-) Moreover, conditional inclusion shouldn't be confused with dynamic scoping or control of "content" (the difference between #ifdef and if (...).) For markup, we're basically talking about an equivalent of querying, whether this be preprocessing by the server or postprocessing by the client. Finally, the basic problem with using MSs to kludge this is that SGML's default of INCLUDE for status specification is in the way (otherwise the common {something=>true,nothing=>false} type of fail-soft behavior could be built in.) Nevertheless, I'll throw yet another syntax suggestion into the pot: <![ %cond1; [ ... ]][ %cond2; [ ... ... ]]> (i.e. MSC-DSO closes a MS and opens another one. Wouldn't quite work on the older systems though.) Arjun
