The [IKAT|PureXHTMLTemplating] Template Checking Tool is an RSF application which can be used to verify that one set of RSF templates are "equivalent" to another in terms of their rendering power. This checks that the names and nesting structure of any {{rsf:id}} attributes have been preserved, for example in a roundtrip from developers to designers. This application may be checked out of SVN at [TemplateCheckingTool|https://saffron.caret.cam.ac.uk/svn/projects/RSFTemplateCheckingTool/trunk] and [TemplateChecker|https://saffron.caret.cam.ac.uk/svn/projects/RSFTemplateChecker/trunk], and also executed online at [Template Checking Tool|http://ponder.org.uk/TemplateCheckingTool/faces/check].
