There are examples of XML used for application configuration and in 
template systems, I don't know how much power you intend to give your 
users, but if it boils down to simple display logic and some small 
'macro' calls to a predefined API, you could make some kind of tagged 
language for that implementing basic flowcontroll functionality, 
allowing function calling and definition.

You could look at wxWidgets/wxPython's XRC format, which are a XML 
tagged  format that are used to customize layout of wx forms.

But I don't think there are a implemented any fully usable scripting 
languages like that in Python. But it should not be to much work if you 
don't need many functions.
