We do it this way so the documentation source files can be the same for all Tomcat versions with the correct minimum version being inserted via this property. It makes it a lot easier when we start a new major version as we only have to change the minimum version in one place rather than searching through the documentation to find all the places that reference the minimum version. That only happens during the `ant release` step? Doesn't really affect a regular compile from source situation? Thank you for your response!
