> One of the things I do a lot in my current metadata toolchain is normalise namespace declarations.  For example, all uses of a particular namespace end up with the same namespace prefix.  Often, I also want the declaration of the namespace prefix to happen in a particular place (normally the document element) and to have it removed from all other locations in the document.
> Although none of this has functional implications, it saves space in the final document (sometimes quite a lot) and makes it much easier to understand what is going on if you have to look at the XML for any reason.  I think this will look even more useful once we start mixing together metadata from multiple sources with different conventions.
> At the moment, I perform this function with lots of XSLT to normalise cases that come up for us, and I could continue in that vein using XSLTStage.  However, that approach can't be as generic as I'd like, and probably won't work very well when I start merging in metadata from other federations.  So, I'd like to have a stage available that can perform this kind of operation by traversing the DOM directly.
