Lintian tag information: doc-package-depends-on-main-package (type: warning)

Description (from lintian-explain-tags)

The name of this package suggests that it is a documentation package. It
is usually not desirable for documentation packages to depend on the
packages they document, because users may want to install the docs before
they decide whether they want to install the package. Also, documentation
packages are often architecture-independent, so on other architectures the
package on which it depends may not even exist.
