Hi Ludovic, Yes, the interface description is interpreted at runtime, though it is amost immediately converted to SXML, an S-expression-based representation that is isomorphic to the original XML. The C structures that are used during rendering are tightly bound to the spine of this S-expression (which is just a list). I'm open to the idea of a "compiled" document, but it'd need to somehow maintain a mapping to the structure of the original document, since event-handling scripts need to be able to refer to this structure via the DOM -- for exaple, in order to dynamically add and remove UI elements. I was planning to add other rendering targets, such as GTK+, but I wanted to see if there was any way to use existing libraries -- such as, say, Mozilla Gecko -- before really diving in on that one.
Thanks for your remarks!
