XML as a code reuse methodology is a very complex and technical topic. Instructional designers who seek to discover the impacts of XML to instructional design are very often frustrated by the technical white papers available on this subject. Those white papers usually fail to speak to the practical needs of instructional design. This article is written for experienced instructional designers who wish to understand content reuse in an XML environment. It explains the basic underlying concepts at a non-technical level and relates those concepts to instructional design processes. Tools and options are discussed. The effects of code reuse are described for both print and online curricula. The costs, risks and benefits of both off-the-shelf and custom systems are examined.
