SharePoint: Adding Custom Field in Content Query Webpart

Found this article at MSDN and ECM Team Blog which describe how to add a custom field into the presentation of content query webpart. The process involve two major work:

1. Export content query webpart into a dwp file, and add the custom fields.

2. Modify the XSLT to define the presentation for the custom field. The XSLT file is located in the folder Style Library à XSL Style Sheet àItemStyle.xsl, which you’ll need SharePoint Designer to access and modify.
