I realy like xml formating but its work not so fast as basic 
colon-separated format of header.info.
But it's your choice - i just want to make sort of standart for this. :)

Because not all of http servers give a Content-Length for example.
And not all of ftp daemons support SIZE command. If you want to show user
"Now updater download %s packages with size %s" you need to know size of
each files.

I need lots of information about downloaded file (size, md5 summs, 
timestamp and so on).
I think what yum users also want to see size of downloaded files and 
check md5summ for header.info for example.
So i think to standartize format of file what describe all this stuff.
