Description of problem:

In Fedora 8, language support groups are tagged as <langonly>.
In Fedora 9, language support groups are tagged as <lang_only>, but yum itself
assumes <langonly> when selecting package group.

In Fedora 8, conditinal packages are like below:
<packagereq type="conditional"
requires="xorg-x11-server-Xorg">scim-anthy</packagereq>
In Fedora 9, like below:
<packagereq type="conditional"
requires="scim-anthy">xorg-x11-server-Xorg</packagereq>
