[Spacewalk-list] [centos-errata.py] Hidden errata for CentOS 5 in CESA-2012:0324 (CentOS 6)

[Yungwei Chen]

Hi,

I noticed that some CESA items for CentOS 6 also applies to CentOS 5, such as CESA-2012:0324. 
But centos-errata.py simply outputs the following for CESA-2012:0324:
 Message '[CentOS-announce] CESA-2012:0324 Moderate CentOS 6 libxml2 Update' is inapplicable to the targeted CentOS release
 Failed to process subject [CentOS-announce] CESA-2012:0324 Moderate CentOS 6 libxml2 Update

But according to https://rhn.redhat.com/errata/RHSA-2012-0324.html,
"Updated libxml2 packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6.

Is there a better way to address this issue besides manually creating an errata for each occurence? Thanks.
