The following line outputs 0, which is surprising ...
<xsl:value-of select="count(document('')//*)" />

Vb.NET code is something like this ...
  xsl = New System.Xml.Xsl.XslTransform()
  url_rslv = New System.Xml.XmlUrlResolver()
  url_rslv.Credentials = System.Net.CredentialCache.DefaultCredentials
  xsl.XmlResolver = url_rslv
  xsl.Load(xslTmp.CreateNavigator)
  xw = New System.IO.StringWriter()
  xsl.Transform(xmldoc.CreateNavigator, Nothing, xw)
  Console.Write(xw.ToString)
