> 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 for a use case.
