In {{{_common-migrate-element}}}, {{{_common.xsl}}} copies all nodes on
the namespace axis except the one that has the same namespace URI as the
current element.
That does, however, also copy over a plain {{{xmlns}}} declaration from
another namespace, which in some cases can lead to weird results, such as
this one I came across whilst working on config handlers for
milestone:1.1, where this:
{{{
#!xml
<?xml version="1.0" encoding="UTF-8"?>
<ae:configurations
xmlns:ae="http://agavi.org/agavi/config/global/envelope/1.0";
xmlns="http://agavi.org/agavi/config/parts/config_handlers/1.0";>
<ae:configuration>
<handlers>
}}}
is converted to:
{{{
#!xml
<?xml version="1.0" encoding="UTF-8"?>
<configurations xmlns="http://agavi.org/agavi/config/global/envelope/1.1";
xmlns:default="http://agavi.org/agavi/config/parts/config_handlers/1.1"; >
<default:configuration
xmlns="http://agavi.org/agavi/config/parts/config_handlers/1.1";>
<default:handlers>
}}}
The {{{<configuration>}}} element here ends up in the content namespace
since the XSLT processor seems to shuffle namespace prefixes around a bit,
and our copying of the {{{xmlns}}} attribute gets in the way.
The purpose of copying {{{xmlns:foo}}} declarations is to make sure that
they remain available as originally declared, which usually is only
relevant in cases where element or attribute content refers to the
declared prefixes again, think {{{<xs:element type="foo:burp" />}}}. We
need that mainly for SOAP, WSDL and stuff like that.
As a fix, we can simply suppress the copying of an {{{xmlns}}} attribute,
since that's useless anyway.
