Fixes Invalid tag name error when using k:v tagname

This patch fixes the invalid tag name error when k:v type
tagname appears in response of api during xml serialization,
the tagname which contains colon couldn't be supported by
default since it is reserved by xml namespace, this patch
solve it by adding the k of k:v tagname into namespace.
