Title: allow a processing instruction to appear multiple times

My use case is to use a processing instruction to group common elements
that will appear multiple times.

````

org.jboss.as.messaging

...

````

It is not possible currently as the COMMON_CONFIG can only appear once
in the XML.
Using a set of processing instructions allow to reuse the same
processing instructions at different places in the XML.
