We already had a conf call about that one and agreed on that tag.

SUSE is already using it, in our repomd.xml extension file, called 
suseinfo.xml

curl http://download.opensuse.org/update/11.3/repodata/suseinfo.xml

<?xml version="1.0" encoding="UTF-8"?>
<suseinfo xmlns="http://linux.duke.edu/metadata/repo">
<expire>2592000</expire>
</suseinfo>

We use the same parser for repomd.xml and suseinfo.xml. That means, if 
you put that tag in repomd.xml next to the "tags" tag, we remain 
compatible. We just kept it in suseinfo.xml to not break compatibility 
with yum.
