Sitemap + XSLT Pipelines versus MVC Frameworks

I've been learning about model-view-controller (MVC) application frameworks lately thanks to the awesome Perl-based Catalyst project.

So far I'm able to make these comparisons:

• Sitemap = Controller
• Datasource = Model
• Templates = View

Its not that simple though, as there is no object relationship mapping in Nexista, so the datasource / model comparison is very rough.
