I will have the pleasure of speaking twice at XML Prague 2009, once on my own and once as a co-presenter:

• Testing XSLT — An update and expansion of my previous talk on testing XSLT presented in less time.  How can that be?  Simple, really: put more in the conference paper, direct attendees to the paper, and spend more of the presentation doing demonstrations.
• Imagining, building and using an XSLT virtual machine — The why and what of the open source Xcruciate XML-based server.  Or the why, what, and Howe of Xcruciate, since I’m the second presenter with Mark Howe of Cyberporte, who provides the ideas behind Xcruciate and its related projects.
