Re: [xml-dev] [Ann - Zvon] Templatotron
So far as i understand TAL it is used to analogous ends as are proposed for Templatotron. Analogous, rather than identical, in that input objects are data instances rather than documents. My concern is with the expressiveness rather than the implementation. To be more direct, the use of the distinguished namespace for element identifiers in order to trigger transformations introduces the need for additional operators to specify target namespaces. TAL, on the other hand, triggers on attributes. Which leaves the element identifer's namespace unencumbered and permits the "same" transformation to be expressed with fewer terms. I would expect that one could do the same with XSLT and was curious why one didn't. ...
