           Summary: Serializer doesn't handling inconsistent prefixes
                    properly
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: XML
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: alex at milowski.com


When constructing an XML document programmatically, the namespaces in use and prefixes may be inconsistent.  For example, the results of merging cloned nodes from different sources may end up with conflicting prefix to namespace mappings.  These conflicts must be detected and the prefixes adjusted.

The current implementation allows multiple namespace attributes for the same prefix which results in an XML parsing error for any receiving application.
