ThirdParty/libxml2/vtklibxml2/tree.c:9770–9820

* xmlDOMWrapAdoptAttr: * @ctxt: the optional context for custom processing * @sourceDoc: the optional source document of attr * @attr: the attribute-node to be adopted * @destDoc: the destination doc for adoption * @destParent: the optional new parent of @attr in @destDoc * @options: option flags * * @attr is adopted by @destDoc. * Ensures that ns-references point to @destDoc: either to * elements

* Returns 0 if succeeded, -1 otherwise and on API/internal errors.
