All reports of xc-package-type-in-debian-control for the archive. The extended description of this tag is:
The debian/control file contains an XC-Package-Type field. As of dpkg-dev 1.15.7, the dpkg development utilities recognize Package-Type as an official field name and do not add it to binary packages (the previous concern with the dpkg-dev-supported Package-Type field). XC-Package-Type should generally now be replaced with Package-Type.
This tag has not been emitted in any package tested by Lintian.
