0005648: Category field in CentOS-6 is lacking a number of items

I don't have a complete list but there are apparently many package names missing in the Category field for CentOS-6. For example, openssh and openssl are there but openssh-xxx or openssl-xxx are not listed (see examples).<br /> <br /> openssh-askpass<br /> openssh-clients<br /> openssh-lda<br /> openssh-serve<br /> <br /> openssl-devel<br /> openssl-perl<br /> openssl-static<br /> openssl098e
