XML has its own rules, so unless tools take a specific prefix for granted, everything should be OK. One can also declare full module names as NS prefixes in XML encoding to make it closer to JSON encoding. The only minor problem is the paragraph in sec. 7.1.4 of RFC 7950 stating that XML and XPath SHOULD use the prefix defined in YANG. IMO, this should be removed (but, after all, it is only a SHOULD).
