title: text center justified in openxml Word document
body: <p>I am trying to apply formatting to text using open xml. I would like to add Bold, 18 pt font and have it centered. </p>
  
  <p>The bold and font size formatting applies correctly but I cannot get the <em>center justification</em> to work. This is my first use of open XML, any help is much appreciated.</p>
  
  <pre><code>Dim mainPart As MainDocumentPart = mydoc.AddMainDocumentPart() 
  mainPart.Document = New Document()
  Dim body As New Body()
  Dim paragraph As New Paragraph()
  Dim run_paragraph As New Run()
  'we want to put that text into the output document 
  Dim text_paragraph As New Text("Executive Summary - " + name)
  'Append elements appropriately. 
  
  'bold
  Dim RunProperties As RunProperties = run_paragraph.AppendChild(New RunProperties())
  Dim Bold As New Bold
  Bold.Val = OnOffValue.FromBoolean(True)
  Dim fontSize As New FontSize
  fontSize.Val = "22"
  RunProperties.AppendChild(fontSize)
  RunProperties.AppendChild(Bold)
  
  'center
  Dim paragraphProperties As ParagraphProperties = run_paragraph.AppendChild(New ParagraphProperties())
  Dim justification As New Justification
  justification.Val = JustificationValues.Center
  paragraphProperties.AppendChild(justification)
