Bug 1528705 [wpt PR 15389] - XMLSerializer should drop xmlns="..." in some cases, a=testonly Automatic update from web-platform-tests XMLSerializer should drop xmlns="..." in some cases If an element has no prefix and its namespace is different from the current default namespace, the element needs to add xmlns="<elements-namesapce-uri>". In such case, we need to drop existing xmlns="<other-uri>" and need to take care of existing xmlns="<elements-namespace-uri>". Implementation: Follow the specification in the following points: - Stop registering default namespace to prefix-namespace / namespace-prefixes maps. - The default namespace is tracked by NamespaceContext:: context_namespace_. - 'local default namespace' is computed in 'recording the namespace information' algorithm. * NamespaceContext::Add(): Make sure arguments are not empty. * Move MarkupAccumulator::RecordNamespacInformation to NamespaceContext, and update the default namespace handling. * AppendElement() respects to 'ignore namespace definition attribute' flag. * Implement some parts of the specification to - keep track the default namespace - return correct 'ignore namespace definition attribute' value - add an appropriate xmlns="..."
