Aquent Graphics Institute (AGI Training) is another resource for XML, XSLT, XSL-FO, and XML Schema training. AGI uses OxygenXml as the XML editor in our classes. We also use this in our advanced Adobe Dreamweaver training classes and Adobe InDesign training where XML is involved. More information about the training classes in Boston, New York, and Philadelphia is here: Dreamweaver and XML: http://www.agitraining.com/pages2/dreamweaver.html
and InDesign and XML: http://www.agitraining.com/pages2/indesign.html

I hope this is helpful.
