XOM API for Processing XML with Java

[Wolfgang Hoschek <whoschek AT lbl.gov>]

If one wanted to recreate the exact same XOM document, preserving  
additional namespace declarations "as is" is key. In this context  
it's not really relevant to what extent model XYZ treats things as  
different or identical; I'd like things round-tripped "as is", under  
any and all circumstances. The only efficient way I found to do this  
is via a new method getAdditionalNamespaceDeclarations(), as outlined  
before.

[Incidentally this speeds up bnux over namespaced documents by a  
factor 3, both on serialization and deserialization, now closely  
matching performance on documents that have no namespaces at all.]
