It would be good to expand a bit on what you are looking to do.

Are you looking to change the system-wide default or are you looking for 
the container/app server to see a different default to the applications 
that it runs?

As things currently stand then then default can be overridden by 
deploying the XML parser on the class path or as a service provider 
module on the module path. The JPMS requirements document includes a 
requirement for ordering service providers that isn't implemented yet. 
If/when that happens then it might help with part of this.
