A while back I posted a scanning tool to detect the presense of Custom XML Markup in Open XML documents.
I wanted to provide an update for this tool to reflect the new Open XML SDK 2.0. The scanning tool has been recompiled against the new version of the SDK and should work a little better. Apart from that, I think the tool is the same. I don't think this one is lighting up the hit / download counts on my blog, but I wanted to post the update just in case. The attachment is a ZIP of an MSI. The tool is provided with no support or warranty, as is.
