That could be what you want. However I don't think all viewers have implemented this method, so in practice you're probably stuck with grouping your texts somehow, and making them visible depending on zoom level. It's also possible to implement yourself (in script) a function that checks the boundingboxes of the text elements against a rect of your choice. My guess is that Andreas Neumann already has some examples of how to do that, see http://www.carto.net. And I would recommend using display:none over visibility:hidden, especially if you have many elements in your tree.
