Thanks senny. Can you tell more exactly what you think is clumsy?
(nXhtml contains a lot of multi major modes and other things related
to web programming.)

But can you please tell what it was that did not work for you?

I have made some optimisations since then (or rather removed some
mistakes). If it feels slow you can also byte compile the whole
nXhtml. (There is a menu entry in the nXhtml menu for that to make it
easier.)

But of course any multi major mode solution that is dynamic and checks
for chunk boundaries while you are editing is doing a little bit more.
However I do not think you will notice it very much normally. If you
have an example where it feels slow I would be glad to know. (Please
try the latest version then.)

You mean bugs, or? Unfortunately I have no idea what you mean unless
you tell me more.

Hm. What do you mean? This exactly what nXhtml gives you, isn't it? Do
you mean that you are not looking for a flexible solution?

If you are missing some special template language then please tell me.
