•  added the XAdES reference for Action 78
• changed one closing tag <:XPath> to </XPath> as pointed by Bruce http://lists.w3.org/Archives/Public/public-xmlsec/2008Oct/0012.html
• changed the comment in this sample to mention that ns1-ns99 namespaces are not used, and empty e2 element is repeated 100 times
