All reports of web-application-depends-on-apache2-data-package for the archive. The extended description of this tag is:
The package appears to be a web application but declares a package relation with apache2-bin, apache2-data or any of its transitional packages. However, web applications are rarely bound to a specific web server version. Thus, they should depend on apache2 only instead. If a web application is actually tied to a particular binary version of the web server a dependency against the virtual apache2-api-YYYYMMDD package is more appropriate.
