Of course. I just thought it was a good time to mention it.

I think so to. I have seen some areas where some form of coherence is 
necessary:

- fontification
- indentation
- parsing

I think nxml-mode is a very good candidate for those that can be used in 
a multiple-major-mode buffers, since a mix of for example XHTML and PHP 
is common.

This might seem impossible, since such code could not be valid XHTML. 
Actually it is not, the rng parser used in nxhtml-mode is quite good on 
guessing an apropriate state for completion. (But do not ask me what the 
rng parser does, I do not understand it.)
