Andreas Veithen commented on AXIS2-3229:
----------------------------------------
@Tharindu: The schema document may be outdated, but that doesn't mean that the
namespace URI is outdated. BTW, if you look at the up-to-date version of the
schema, it uses the exact same namespace. Anyway, the "Namespaces in XML 1.0"
spec [1] is the only authoritative document that describes the usage of the
"xml" prefix:
"The prefix xml is by definition bound to the namespace name
http://www.w3.org/XML/1998/namespace. It MAY, but need not, be declared, and
MUST NOT be bound to any other namespace name. Other prefixes MUST NOT be bound
to this namespace name, and it MUST NOT be declared as the default namespace."
Not sure though if that discussion really has something to do with the actual
issue.
