Norm Tovey-Walsh is a Senior Software Developer at Saxonica. He has also been an active participant in international standards efforts at both the W3C and OASIS. At the W3C, Norm was chair of the XML Processing Model Working Group, co-chair of the XML Core Working Group, and an editor in the XQuery and XSLT Working Groups. He served for several years as an elected member of the Technical Architecture Group. At OASIS, he was chair of the DocBook Technical Committee for many years and is the author of DocBook: The Definitive Guide. Norm has spent more than twenty years developing commercial and open source software. Debbie Lockett joined Saxonica back in early 2014 in the days of Saxon 9.6; when XPath 3.0 and XQuery 3.0 were brand new, and XSLT 3.0 was approaching "last call working draft" status. She had no idea what any of these things meant, and has learned everything she knows about software development and XML technologies while at Saxonica. Debbie previously worked as a post-doctoral researcher in Mathematics at the University of Leeds, writing papers on symmetries of infinite relational structures, and once taught an undergraduate course to a class of 200 students. Debbie has worked on SaxonJS since its inception in 2016, and is now a lead developer.
