When I use the following pom.xml in order to allow an XSD for my custom plugin
configuration:
{code:xml}
<project xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns="http://maven.apache.org/POM/4.0.0";
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

It would be awesome if the XML parser would resolve namespaces properly. Its
not about adding namespace features, only for plain XML resolving (each decent
XML these days should be able to do this transparently).
Except for
https://cwiki.apache.org/confluence/display/MAVEN/Moving+forward+with+the+POM+data+model
I couldn't find any statement when namespaces are supported or tolerated. Are
there any plans for this (and maybe also to relax the schema constraints on the
{{<configuration>}} tag) ?
See also https://github.com/rhuss/poblano/issues/19 got a use case.
