...ttribute

It seems that the location element in repomd.xml which is supposed to contain href attribute with location as the value was not done correctly in the new distributor -  
eg. expected value is 
<location href="repodata/filelists.xml.gz"/>
as opposed to 
<location>repodata/filelists.xml.gz</location>
