#2 XMLReaderElement::interpret() doesn't detect a missing closing tag

  XMLReaderElement reader("elem");

  reader
    .RawData(elementXml)
    .Element("stage", stageContent)
      .RawData(stageXml)
      .End("stage")
    .End("elem");

When parsing ```<elem><stage>Content></elem></stage>``` with ``` XMLReaderElement reader("elem"); reader .RawData(elementXml) .Element("stage", stageContent) .RawData(stageXml) .End("stage") .End("elem"); ``` XMLReaderElement::interpret() does not return any error. It should detect the invalid XML syntax.
