I hate when I reply to my own messages, but I think some additional remarks are granted here.

One still could conceived an automatic cleaning mechanism, but I am not sure you can enforce it, unless you know what the name is used for. You could say something like: <macrodef...> <let name="temp"/> <onExit clean="property" name="$(temp)"/> <onExit clean="property" prefix="$(temp)"/> <onExit clean="reference" name="$(temp)"/> <onExit clean="macro" name="$(temp)"/> <sequential ..../> </macrodef> Or whatever other name spaces we have. Now this all can be done as the need arrive. Anywhere where we can define something with a name, a recursive macro may want to create new versions of it. And I have used such things on scripts, for example. So it is not just pie in the sky. :-) Jose Alberto --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
