When you construct the template node, you work with Variable objects, which
represent the context variable as it exists in the template source (eg,
html).
At the point where you actually render your output, you want to resolve that
Variable, so that the template framework actually determines what the
contents of that variable should be, given the current context.
The example at
https://docs.djangoproject.com/en/1.3/howto/custom-template-tags/#passing-template-variables-to-the-tag
shows
how it should be done. Construct a Variable object in node.__init__(), and
use variable.resolve(context) in node.render()
