But still, I think using the above ElementTest would be legitimate in some cases, mainly: 1/ if SA is not available. In this case, the best one can achieve is to use element(). SA is great, but there are several reasons one can not have it (one example is an open source stylesheet, the developer wants to broaden as possible the number of processors its stylesheet will be able to run on;) 2/ in a multi-schemas transformation, where some schemas are completely independent, defined by different organizations, I can think of situations where one wants to write a function that will accept some well-identified elements from those schemas, but does not want to write a schema only to create an (artificial) link between them. More generally, I think the schemas define the grammar of valid XML instances, while the stylesheet functions and named templates define processing on those instance, and the rules for parameter typing can be different from the rules of the grammar...
