That would have been useful, for the situation where the macro can degrade properly (i.e ignore the value and/or provide a reasonable default). For example, my macro builds a sidebar with some standard user information in Debian http://wiki-debian-net.klabs.be/User/JohnDoe source is: http://wiki-debian-net.klabs.be/-plugin/macro/DebianPortfolio.py The macro accepts a lot of optional parameters. Actually I have implemented a built-in help, that can be displayed with: <<DebianPortfolio(showhelp=yes)>> see the bottom of http://wiki-debian-net.klabs.be/DebianPortfolioMacro So for example: * All fields are optional. Still I would print the help when all the fields are empty. * The email is important, but not compulsory. * I might want to add some other important fields later... And warn the user when he/she edits the page, but not visitors.
