hi, all an XML tag cannot contains space in it. see https://www.w3.org/TR/2008/REC-xml-20081126/#NT-NameChar. Ceph uses `xmlformatter` to dump XML text, and there are a lot of space in xml tag currently. so, need we fix this? We could fix this as : 1. simple solution: replace `space` with `_` 2. urlencode: \n = 
 \r = 
 \t = 	 space =   any comments are appreciated! -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
