One of the intriguing things about doing this in Lua is that when you associate a function with each tag, you could use the environment of that function to store attributes atttached to that tag...so they become "globals" for that tags function and its children. To make this really useful, though, the environments would also have to be chained via __index, or a bridging global such as _parent...
setfenv(newTag, {_parent = getfenv(1)})
...or something along those lines.

My hope is that I can use it for a templating "language". I could feed in a single table and then use lexical scoping within the nested functions to return a given value.
