I don't think there's a public function in Libxml2 which does
what you want.
What I currently use to avoid creation of namespace declarations
is the following:
- Walk the tree to be copied on your side.
- Build the resulting tree-copy on your side.
- Use xmlDocCopyNode() with an @extended argument of 0. Doing this
  will only copy the rudimental element node; i.e. no ns-decls, no
  children and no attributes.
- Copy the already existent ns-decls on your side.
- Copy attribute nodes on your side.
- Finally use xmlDOMWrapReconcileNamespaces() to ensure that
  node->ns entries point to in-scope ns-decls.

Actually a public version of xmlStaticCopyNode() would do the
job you want if you have a @parent argument at hand. It would
search the ns-decls of the destination tree as well, thus would
avoid creation of redundant ns-decls.
Does anyone see problems wrt adding a public wrapper for
xmlStaticCopyNode() which also takes a @parent argument?

However, in the long term I would like to add a function
similar to xmlDOMWrapAdoptNode(), which does a copy of the
tree and provides customizable handling of ns-references.
